It is not possible to solve the triangle with the given information.
What is Triangle ?
A triangle is a polygon with three sides and three angles. It is one of the basic shapes in geometry and is widely used in mathematics, science, and engineering. Triangles can be classified in different ways based on their side lengths, angle measures, and other properties.
To solve a triangle, we need at least three pieces of information, including at least one side length. In this case, we have the side lengths a=100 and b=90, and the angle opposite side a is 29 degrees. However, we don't have enough information to find the remaining angles and side lengths of the triangle.
We can use the Law of Cosines and the Law of Sines to solve a triangle, but we need at least one more piece of information. For example, if we had the length of side c or another angle, we could solve the triangle.
Therefore, It is not possible to solve the triangle with the given information.

(Perimeter and Area on the Coordinate Plane MC) Which of the following is the fourth vertex needed to create a rectangle with vertices located at (–5, 3), (–5, –7), and (5, –7)? (5, –3) (5, 3) (–5, 7) (–5, –3)
Step-by-step explanation:
To create a rectangle with vertices located at (-5, 3), (-5, -7), and (5, -7), we need to find the fourth vertex that completes the rectangle. Since opposite sides of a rectangle are parallel and congruent, we can determine the missing vertex by finding the midpoint of either of the two given sides and then moving in the direction perpendicular to that side by the length of the other side.
The given sides are:
Side 1: (-5, 3) to (-5, -7), which has length 3 - (-7) = 10
Side 2: (-5, -7) to (5, -7), which has length 5 - (-5) = 10
Since the sides are congruent, we can find the midpoint of Side 1 as:
Midpoint of Side 1 = [(-5 + (-5))/2, (3 + (-7))/2] = [-5, -2]
To find the missing vertex, we need to move from (-5, -2) in the direction perpendicular to Side 1 by a distance of 10 units (the length of Side 2). Since Side 2 is horizontal, we need to move vertically. We can do this by adding or subtracting 10 from the y-coordinate of the midpoint of Side 1, depending on whether we want to move up or down. In this case, we want to move down, so we subtract 10:
Missing vertex = [-5, -2 - 10] = [-5, -12]
Therefore, the fourth vertex needed to create a rectangle with vertices located at (-5, 3), (-5, -7), and (5, -7) is (-5, -12).
Select the correct answer from the drop-down menu. The design for a two-tank system is shown. The inner tank must be surrounded by oxygen with a density of 0.0827 pounds per cubic foot. Diagram shows a small rectangular prism placed inside a large rectangular prism. Small prism has a length of 5 feet, a width of 4 feet, and a height of 3 feet. Large prism has a length of 20 feet, a width of 8 feet, and a height of 6 feet. What amount of oxygen is needed in the outer tank? To meet the density required, approximately pounds of oxygen is required.
Answer:
74.43 pounds
Step-by-step explanation:
To find the amount of oxygen needed in the outer tank, we need to first find the volume of the space between the two tanks. This space is a rectangular prism with length 20 feet, width 8 feet, and height 6 feet, but with a rectangular prism removed from the center. The removed prism has length 5 feet, width 4 feet, and height 3 feet.
The volume of the rectangular prism between the two tanks is:
V = (20 x 8 x 6) - (5 x 4 x 3)
V = 960 - 60
V = 900 cubic feet
To find the amount of oxygen needed to fill this space with a density of 0.0827 pounds per cubic foot, we can multiply the volume by the density:
m = V x d
m = 900 x 0.0827
m ≈ 74.43 pounds
Therefore, approximately 74.43 pounds of oxygen is required to meet the density requirement.
Answer: 74 pounds
Step-by-step explanation:
(20*8*6) - (5*4*3)
960-60
v=900 ft3
density=0.0827
mass=0.0827*900
Mass is 74 pounds

Find the value of x.
Answer:
x = 8°
Step-by-step explanation:
∠GJL = ∠WJZ = 90° - 18° = 72° (cross angles)
(9x)° = 72° / : 9
x = 8°
Answer:
x = 8
Step-by-step explanation:
Find the measure of angle WJZ.
Since angles on a straight line sum to 180°:
⇒ m∠GJH + m∠HJW + m∠WJZ = 180°
⇒ 90° + 18° + m∠WJZ = 180°
⇒ 108° + m∠WJZ = 180°
⇒ 108° + m∠WJZ - 108° = 180° - 108°
⇒ m∠WJZ = 72°
According to the Vertical Angles Theorem, when two straight lines intersect, the opposite vertical angles are congruent.
Since line GJZ and line LJW intersect, then ∠GJL and ∠WJZ are vertical angles and therefore congruent:
⇒ m∠GJL = m∠WJZ
⇒ (9x)° = 72°
⇒ 9x = 72
⇒ 9x ÷ 9 = 72 ÷ 9
⇒ x = 8
Therefore, the value of x is 8.

5. Apply logarithm to evaluate T given 644 204 = 400 000(1+10%), by first simplifying the equation.
Answer:
the value of T that satisfies the equation 644 204 = 400 000(1+10%) is approximately 6.45.
Step-by-step explanation:
We can simplify the equation 644 204 = 400 000(1+10%) by first simplifying the percentage term on the right-hand side:
10% of 400 000 is equal to 0.1 × 400 000 = 40 000.
So the equation becomes:
644 204 = 400 000(1 + 0.1 × 1)
Now, we can use logarithms to solve for T:
T = log(base 1.1)(644204/400000)
Using a calculator, we can evaluate the right-hand side to be approximately 0.2, so:
T = log(base 1.1)(1.61051)
Using the change of base formula, we can rewrite this as:
T = ln(1.61051) / ln(1.1)
Evaluating the natural logarithms using a calculator, we get:
T ≈ 6.45

Goods in transit worth K95 480 were insured against damage at k 682 in every K27 200 worth of goods. Find the premium for insuring the goods.
Answer: To find the premium for insuring the goods, we need to determine the total amount of insurance that is needed and then calculate the cost of the insurance based on the given rate.
The total amount of insurance needed is equal to the value of the goods in transit, which is K95 480.
To determine the cost of the insurance, we can use the given rate of K682 for every K27 200 worth of goods. We can set up a proportion:
(K682 / K27 200) = (premium / K95 480)
To solve for the premium, we can cross-multiply and simplify:
K682 * K95 480 = K27 200 * premium
premium = (K682 * K95 480) / K27 200
premium = K1 897.12
Therefore, the premium for insuring the goods is K1 897.12.

please help The triangle below is isosceles. Find the length of side x in simplest radical form with a rational denominator
Answer:
x = 3√2
Step-by-step explanation:
You want the length x of the hypotenuse of an isosceles right triangle with sides of length 3.
Isosceles right triangleThe two legs of an isosceles right triangle are congruent. The length of the hypotenuse can be found from the Pythagorean theorem:
x² = 3² +3²
x² = 3²·2
x = √(3²·2) = 3√2
The length of side x is 3√2.
__
Additional comment
A isosceles right triangle is one of two "special" right triangles. The ratios of its side lengths are 1 : 1 : √2. This tells you the hypotenuse is √2 times the side length, as we found above.
The other "special" right triangle is the 30°-60°-90° triangle. Its side lengths have the ratios 1 : √3 : 2. Both of these are seen often in algebra, trig, and geometry problems.
A giant tortoise can travel 0.14 miles in 1 hour. At this rate, how long would it take the tortoise to travel 3 miles
It would take the giant tortoise approximately 21.43 hours to travel 3 miles at a rate of 0.14 miles per hour.
What is distance?
Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet. Distance is a scalar quantity, meaning it has only magnitude and no direction.
We can use the formula:
time = distance ÷ speed
where "distance" is the total distance to be traveled and "speed" is the rate of travel.
In this case, the distance is 3 miles and the speed is 0.14 miles per hour. So we can substitute these values into the formula and solve for "time":
time = 3 miles ÷ 0.14 miles per hour
time ≈ 21.43 hours
Therefore, it would take the giant tortoise approximately 21.43 hours to travel 3 miles at a rate of 0.14 miles per hour.

A tree casts a shadow 21 m long. The angle of elevation of the sun is 51°. What is the height of the tree? Record your answer in the table below.
Answer:
17.2 meters
Step-by-step explanation:
We can use the tangent function to solve this problem. Let's denote the height of the tree as h. Then we have the following:
tan(51°) = h / distance from the tree to the end of the shadow
We can find the distance from the tree to the end of the shadow by using the length of the shadow and the angle of elevation of the sun. Since the shadow is 21 meters long, and the angle of elevation of the sun is 51°, we can use the following trigonometric relationship:
tan(51°) = h / distance from the tree to the end of the shadow
tan(51°) = h / x (where x is the distance from the tree to the end of the shadow)
To find x, we can use the following trigonometric relationship:
tan(39°) = h / x (where 39° is the complementary angle to 51°)
We can solve for x by rearranging this equation as follows:
x = h / tan(39°)
Substituting this expression for x into the first equation, we have:
tan(51°) = h / (h / tan(39°))
Simplifying this equation, we get:
h = (21 m) * tan(51°) / tan(39°)
Using a calculator, we find h to be the following:
h = 17.2 meters
Therefore, the height of the tree is approximately 17.2 meters.

each containing balls labeled from 0 to 9.
So there are 1,000 possible selections in
total: 000, 001, 002, . . . , 998, 999.
Players can choose to play a "straight"
bet, where the player wins if they choose
all 3 digits in the correct order. Since
there are 1,000 possible selections, the
probability a player wins a straight bet is
1/1,000. The lottery pays $400 on a
successful $1 straight bet, so a player's
net gain if they win this bet is $399.
Let X represent a player's net gain on a
$1 straight bet.
Calculate the expected net gain E(X).
According to the question the expected net gain for a player on a $1 straight bet is -$0.60.
how to calculate expected value in probability?Simply multiply each value of the discrete random variable X by its probability and add the products to get the expected value, E(X), or mean. The formula is as follows: E (X) = ∑ x P (x)
The possible outcomes for X are winning with a probability of 1/1000 and net gain of $399, and losing with a probability of 999/1000 and net gain of -$1. Therefore, we can calculate the expected value of X as follows:
E(X) = (1/1000)($399) + (999/1000)(-$1)
E(X) = $0.399 - $0.999
E(X) = -$0.60
Therefore, the expected net gain for a player on a $1 straight bet is -$0.60. This means that, on average, a player will lose $0.60 for each $1 bet they place on this game.

RSM a pharmisest has a 18 percent alcohol sulution and a 40 percent alcohol sulution how much of each must he use to make 10 leaters of 20 persent alcohol sulution
Answer:
To make 10 liters of 20% alcohol solution, RSM would need to use a combination of the 18% and 40% alcohol solutions. Let's call the amount of 18% solution used "x" and the amount of 40% solution used "y".
To set up the equation, we'll use the fact that the amount of pure alcohol in the final solution must be equal to 20% of the total volume.
So:
0.18x + 0.40y = 0.20(10)
Simplifying:
0.18x + 0.40y = 2
We have one equation with two unknowns, which means we need another equation. Fortunately, we know that RSM is making a total of 10 liters of solution. So:
x + y = 10
We now have two equations with two unknowns, which we can solve simultaneously. One way to do this is to solve one equation for one variable, then substitute that expression into the other equation, like so:
x = 10 - y (from the second equation)
0.18(10-y) + 0.40y = 2 (substituting into the first equation)
1.8 - 0.18y + 0.40y = 2
0.22y = 0.2
y = 0.91
So RSM would need to use approximately 0.91 liters (or 910 milliliters) of the 40% solution, and the rest (9.09 liters or 9090 milliliters) of the 18% solution, to make 10 liters of 20% alcohol solution.

Midpoint = ((-3 + 3)/2, (0 + 0)/2) = (0, 0)
So the center of the circle is at the point (0, 0). The radius of the circle is half the length of the diameter, which is:
Radius = 1/2 * distance between (-3, 0) and (3, 0)
= 1/2 * 6
= 3
Therefore, the equation of the circle with endpoints at (-3, 0) and (3, 0) is:
(x - 0)² + (y - 0)² = 3²
Simplifying:
x² + y² = 9
So the equation of the circle is x² + y² = 9.

What value of x satisfies the system of equations below? x + y = 2 7x - y = 2
Answer:
0.5
Step-by-step explanation:
We want to get an equation with only one variable for it to be able to be solved.
To do this, we will solve the first equation for y.
[tex]x+y=2\\y=2-x[/tex]
Now, we can plug this value of y into the second equation
[tex]7x-y=2\\7x-(2-x)=2\\[/tex]
Finally, we have just one variable, and we can solve for x.
[tex]7x-(2-x)=2\\7x-2+x=2\\8x=4\\x=0.5[/tex]
