Answer:
∠1 = 90° because the figure is a kite and the diagonals form 90° angles
∠2 = 90° - 27° = 63°
∠3 = ∠2 = 63°
Answer:
m<1 = 90 degrees
m<2 = 63 degrees
m<3 = 63 degrees
Step-by-step explanation: Angle 1 is a right angle, which is equal to 90 degrees. To find angle 2, you must know that a triangle's angles all add up to 180 degrees. You must realize that the angle below the 2 is 90 degrees since it is supplementary to angle 1. Now, you have to add the given angle of 27 degrees to 90 degrees and then subtract that sum from 180 degrees to get an answer of 63 degrees (27+90=117 --> 180-117=63). Angles 2 and 3 have the same value because they are basically symetrical to one another since both of their triangle's side lengths are equivalent.

On solving the provided question, we can say that so, we apply permutation P(12,4) = 12!/ 8! = 11880
what is permutation?The permutation of a set in mathematics is essentially the rearranging of its elements if the set is already ordered, or the arrangement of its members in a linear or sequential order. The act of altering the linear order of an ordered set is referred to as a "permutation" in this context. The mathematical calculation of the number of possible arrangements for a given set is known as permutation. Permutation, in its simplest form, refers to the variety of possible arrangements or orders. The placement of the elements matters with permutations. The placement of items in a specific order is known as a permutation. Here, the set's components are sorted in either chronological order or linear order. like in the case of.

Determina en cada caso, si la función corresponde a una función lineal o a una función afín. a. Y = -5x b. Y = -3x – 2 c. Y = 2x + 4 d. Y = 1x/4 – 2
Answer:
Sabemos que una función lineal es de la forma:
f(x) = m*x
Mientras que una funcion afin es de la forma:
g(x) = m*x + n
Entonces para reconocer si una función es lineal o afín, simplemente debemos ver si tenemos un término constante o no (un término constante es un término que no está siendo multiplicado por la variable x).
a) y = -5*x
No tenemos término constante, entonces es una función lineal.
b) y = -3*x - 2
Acá tenemos un término constante igual a -2, entonces esto es una función afín.
c) y = 2*x + 4
Acá tenemos un término constante igual a 4, entonces esto es una función afín.
d) y = (1/4)*x - 2
Acá tenemos un término constante igual a -2, entonces esto es una función afín.

A. Find the area of the base of the pyramid.
B. Find the area of one lateral face of the pyramid
C. Use the net to find the lateral surface area of the pyramid. The base is not included.
D. Use the net to find the total surface area of the pyramid.
Answer:
A. 9 [tex]cm^{2}[/tex]
B. 9.6 [tex]cm^{2}[/tex]
C. 38.4 [tex]cm^{2}[/tex]
D. 47.4 [tex]cm^{2}[/tex]
Step-by-step explanation:
A. Area of the base of the pyramid = length x length
= 3 x 3
= 9 [tex]cm^{2}[/tex]
B. Area of one lateral face of the pyramid = area of a triangle
= [tex]\frac{1}{2}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 3 x 6.4
= 9.6 [tex]cm^{2}[/tex]
Area of one lateral face of the pyramid = 9.6 [tex]cm^{2}[/tex]
C. The lateral surface area of the pyramid = 4 x area of one lateral face
= 4 x 9.6
= 38.4
The lateral surface area of the pyramid = 38.4 [tex]cm^{2}[/tex]
D. The total surface area of the pyramid = lateral surface area of the pyramid + area of the base
= 38.4 + 9
= 47.4
The total surface area of the pyramid = 47.4 [tex]cm^{2}[/tex]

Are 2 sides of an isosceles triangle?
Yes, the lengths of the two sides of an isosceles triangle are equal.
An isosceles triangle is a type of triangle that has two sides that are equal in length. The other side of the triangle can be either longer or shorter than the two equal sides. The two equal sides are called the legs, and the other side is called the base. The angles opposite the two equal sides are also equal in measure. Because of this, the two equal sides create an angle bisector that divides the base into two equal parts. This angle bisector forms two angles of equal measure as well. Thus, the two equal sides of an isosceles triangle are a defining feature of the shape.

A large rectangular box has a volume of 15. 75 cubic feet the box is 2. 5 feet long and 1. 5 feet wide what is the height of the box
A large rectangular box has a volume of 15. 75 cubic feet the box is 2. 5 feet long and 1. 5 feet wide. So the height of the box is 4.2 feet.
The formula to find the volume of a rectangular box is
V = lwh
where l is the length, w is the width, and h is the height.
Given that the volume of the box is 15.75 cubic feet, the length is 2.5 feet and the width is 1.5 feet, we can use the formula to find the height.
V = lwh
15.75 = 2.5 × 1.5 × h
h = 15.75/ (2.5 × 1.5)
h = 4.2
Therefore, the height of the box is h = 4.2 feet

find equation of the line passing through (4,8) and parallel to the line 3x+y=17( Please give workout)
Answer:
y = -3x +20
Step-by-step explanation:
Equation of line: y =mx + b
Where m is the slope and b is the y-intercept.
3x + y = 17
Write the above equation in y = mx +b form.
y = -3x + 17
m = -3
Parallel lines have same slope.
So, slope of the required line is (-3).
y = -3x + b
This line is passing through (4,8). Substitute in the above equation and find the value of 'b'.
8 = -3*4 + b
8 = -12 + b

Step-by-step explanation:
First, start by setting up the equation
these are both same side interior angles, so they both add up to 180
(3x+10) + x = 180
4x+10 =180
subtract both sides by 10

4x=170
divide both sides by 4

MARKING BRAINLIEST!! Use a reference angle to find the exact value of the sine, cosine, and tangent of each angle. -pi. (unit circle) -pi= -180 degrees btw.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, a complete question is in the form:
Use a reference angle to find the exact value of the sine, cosine, and tangent of each angle. 260°
Solution:
There are four quadrants which divides into four equal parts. If θ is the angle:
If θ falls in the first quadrant, the reference angle = θ
If θ falls in the second quadrant, the reference angle = 180 - θ
If θ falls in the third quadrant, the reference angle = θ - 180
If θ falls in the fourth quadrant, the reference angle = 360 - θ
Given 260°, this falls in the third quadrant, hence the reference angle = 260 - 180 = 80°.
In the third quadrant, sine and cosine are negative while tangent is positive. Hence:
sin(260) = -sin(80) = -0.985
cos(260) = -cos(80) = -0.174
tan(260) = tan(80) = 5.67
