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:
We know that sum of all sides of polygon is 360
x + x + 108 +90 +90 = 360
2x + 288 = 360
2x = 360 - 288
2x = 72
Therefore x = 36
