Answer :

67.5 degrees

Let the measure of two equal angles of the triangles is x.

Thus, the angles of the triangles are x, x and 45 degrees.

The sum of the measures of the angles of all triangles is 180 degrees.

Hence, the equation is

x + x + 45 = 180

Solve the equation for x

2x + 45 = 180

2x = 180 - 45

2x = 135

x = 67.5

Therefore, measure of other two angles are 67.5 degrees.

Solve −5x = 15. (1 point)<br><br><br> −3<br> 3<br> 10<br> 20
Luba_88 [7]
Remember you can do anything to an eqautoin as long as you do oit to both sides

-5x=15
try to get 1x by itself

remember
(ax)/a=x when a=a

so
-5x=15
get x
divide both sides by -5
remember to flip sign
(-5x)/(-5)=15/(-5)
x=-3

answer is first one
x=-3

Find the surface area of a square pyramid with a length of 5 cm and a slant height of 8cm.
Tems11 [23]
Area of the square base = 5^2 = 25 cm^2
Area of one of the triangular side = 1/2 * 5 * 8 = 20 cm^2 and there are 4 sides
So the surface area  of while pyramid = 4 * 20 + 25 = 105 cm^2

Volume of the cone = (1/3) pi r^2 h
  = (1/3) pi * 5^2 * 8
  =  209.44  ft^2
