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° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{500}{x}[/tex]
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x = [tex]\frac{500}{tan80}[/tex] ≈ 88.2
