Question

Please help me with this pleaseee

Answer 1

x = 88.2

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° =
`(opposite)/(adjacent)` =
`(500)/(x)`

Multiply both sides by x

x × tan80° = 500 ( divide both sides by tan80° )

x =
`(500)/(tan80)` ≈ 88.2
