To find the area of a polygon use the formula Area = 1/2 x perimeter x apothem
Answer:
Step-by-step explanation:
170=40x+50
170=40x+50 subtract 50
120=40x divide by 40
3=x
Answer:
do we have to find area?
Step-by-step explanation:
Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° =
= 
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x =
≈ 88.2
