Question

A ramp 20 ft. in length rises to a platform that is 18 ft. off the ground. How do you find x, the angle of elevation of the ramp?

Answer 1

The angle of elevation for the ramp is
`theta=64.16^o`

Explanation:

We can use the sine of the triangle to solve for the angle.

`sintheta= 18/20`

`theta=sin^-1(18/20)`

`theta=64.16^o`
