Question

Help with geometry please!!

Answer 1

Answer: x= 146

Explanation:

there are 2 right triangles which would add up to 180. 180 + 108 = 288. the total area of a pentagon is 540. 540 subtracted from 288 is 292. since there are 2 x's you would have to divide 292 into half which would equal 146.

Answer 2

We know that sum of all sides of polygon is 360

Explanation:

x + x + 108 +90 +90 = 360

2x + 288 = 360

2x = 360 - 288

2x = 72

Therefore x = 36
