Step-by-step explanation:

The distance between Casey and the base of the lighthouse is 49 ft.

The angle of elevation refers to the angle formed by the straight horizontal line and an object. The crosshair of an observer is usually above the horizontal. 

The angle of depression is the angle formed by the horizontal and a downward angle to an object. The crosshair of an observer is usually above below the horizontal.

The distance between Casey and the base of the lighthouse can be determined by using the tangent of trigonometry.

The required kite is flying at a height of approximately 45.02 meters to the nearest tenth of a meter.

To find the height at which the kite is flying, we can use trigonometry, specifically the tangent function. The tangent of the angle of elevation (42 degrees) is the ratio of the height (h) of the kite to the distance from Cynthia to the kite (50 meters).

The formula for the tangent of an angle is:

[tex]tan(angle) = opposite/adjacent[/tex]

In this case, the angle is 42 degrees, the opposite side is the height of the kite (h), and the adjacent side is the length of the string (50 meters).

[tex]tan(42^o) = h / 50[/tex]

To find the height (h), we can rearrange the equation:

[tex]h = 50 * tan(42^o)[/tex]

Now, let's calculate the height:

[tex]h =50 * tan(42^o)[/tex]

h ≈ 50 meters * 0.9004
h ≈ 45.02 meters (rounded to two decimal places)

So, the kite is flying at a height of approximately 45.02 meters to the nearest tenth of a meter.

The length of the repel line using one of the 3 trigonometry ratios will be 186.78 feet.

From the information given, Peyton is walking her dog, Willow, on a local trail and the dog falls 153 feet down a ravine.

The length will be calculated thus:

Cos 35° = 153/AC.

AC = 153/cos 35°

AC = 153/0.819

AC = 186.78 feet.

The circumference of the circle is 72cm.

[tex]Arc length = 2\pi r(\frac{x}{360} )[/tex]

where

r is the radius of the circle

x is the central angle of the arc

Circumference of the circle or perimeter of the circle is the measurement of the boundary of the circle. It is calculated as

circumference of the circle = 2πr

According to the given question we have

central angle of the arc, x = 15 degrees

Arc length = 3 cm

Let r be the radius of the given circle.

Then,

Arc length = 2πr[tex](\frac{15}{360} )[/tex]

Answer:

Step-by-step explanation:

4x + 4y = -37

2x + 5y = -17

we are told to use elimination ,   instead of substitution,

meaning get rid of the x or y  in one of the equations.

Part C :   let's multiply (2x + 5y = -17 ) *  (-2)  so we get

-4x - 10y = 34    , then add

4x + 4y = -37

0x -6y = -3      now we have only one variable ,  y

because both sides have a minus sign, we can just drop it

6y = 3   ( divide both sides by 6)

y = 3/6

Part B : y = 1/2    we now know y

plug in the y value into  1st equation.

4x + 4(1/2) = -37

now solve for x

4x + 2 = -37

4x = -39

Part A :  x = - 39/4

2y+3y=−5

5y=−5(Simplify both sides of the equation)

5y/5=−5/5 (Divide both sides by 5)

The solution to the system is x = -1.8 and y = -1.8.

A group of two or more equations that must be solved simultaneously make up a system of equations. There are many unknown variables in a system of equations, and each equation in the system depicts the relationship between those variables.

A set of variable values that satisfy every equation in a system of equations is the solution to the system of equations.

To solve this system of equations graphically, we can plot the two equations on a coordinate plane and find the point where they intersect, which represents the solution to the system.

a) To plot the equation x - y = 0, we can rearrange it to y = x and plot the line passing through the origin and the point (1, 1), as shown below:

Graph of the line y = x passing through the origin and the point (1, 1).

To plot the equation 2x + 3y = -5, we can rearrange it to y = (-2/3)x - 5/3 and plot the line passing through the points (-2, 1) and (1/3, -5/3), as shown below:

Graph of the line y = (-2/3)x - 5/3 passing through the points (-2, 1) and (1/3, -5/3).

b) The point where the two lines intersect is the solution to the system. From the graph, we can see that this point is approximately (-1.8, -1.8).

Therefore, the solution to the system is x = -1.8 and y = -1.8.
