Answer:
Each base angle would be equal to 36 degrees.
Step-by-step explanation:
In order to find the base angle measurements, we need to note that both angles would be equal to each other because it is an isosceles triangle. So, we subtract the vertex angle and then we divide by 2 to get the base angle measurements.
180 - 108 = 72
72/2 = 36 degrees
So we know a pyramid has 4 triangles and 1 square
All the triangles are equal, so this means that we need to do our area of the side times 4 to know the total above ground area of the pyramid.
4x27 = 108 cm²
Now the bottom is given so we just add the number to the others:
108+36= 144 cm²

Answer:
3y
Step-by-step explanation:
(-9x+7y)-(-9x+5y)
Distribute the negative(-)
-9x+7y+9x-5y
-9 and 9 cancel each other
3y
