Question

A firefighter is attempting to escape a burning building. If the window is of the man's apartment is 18 feet above the ground and the ladder is 25 feet long, what is the angle of elevation?

Answer 1

37.75⁰

Explanation:

Height of the building = 18 feet (vertical height)

Height of the ladder = 25 feet (Hypotenuse)

We solve this using tan θ =
`(adjacent)/(hypotenuse)`

therefore θ = tan⁻¹ (
`(18)/(25)`)

θ (Angle of elevation) = 37.75⁰
