A=(a+b/2) x h
a = 8
b = 14
h = 14
(8+14/2) x 14
(22/2) x 14
11 x 14 = 154
The answer is 154

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
You need to know these two formulas:

For example,
