Question

25. Angle of Elevation An engineer erects a 75-foot vertical

cellular-phone tower. Find the angle of elevation to the top
of the tower from a point on level ground 95 feet from its
base.

Answer 1

38.29°

Explanation:

The angle of elevation to the top of the tower :

Opposite side = vertical height of tower = 75 feets

Adjacent = 95 feets = horizontal lengtb of base

Using the trigonometric relation :

Tan θ = opposite / Adjacent

Tan θ = 75 / 95

Tan θ = 0.7894736

θ = tan^-1(0.7894736)

θ = 38.29°
