    Answer:

    38.29°

    Step-by-step 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°
