Answer 8

okok.

Answer 9

1) It's a regular pentagon so all sides need to add up to 540 degrees
2) so now we just gather all the sides and equate it to 540, notice at the bottom left is the right square, that represents it's a right angle(90 degrees).

so 90+148+2x+10+2x+112 = 540
4x + 360 = 540
4x = 540 - 360
4x = 180
x = 180/4
x = ????
last step is for you to solve, make sure you understand it.
