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

Answer:

37.75⁰

Step-by-step explanation:

Height of the building = 18 feet (vertical height)

Height of the ladder = 25 feet (Hypotenuse)

We solve this using tan θ = $\frac{adjacent}{hypotenuse}$

therefore θ = tan⁻¹ ($\frac{18}{25}$)

θ (Angle of elevation) = 37.75⁰
