    Question

    A man 1.5 m tall is 22.5 m away from a tower 24 m high.

    Determine the angle of elevation of the top of the tower from the eye of the observer.
    A 60° Correct Answer Incorrect Answer
    B 30° Correct Answer Incorrect Answer

    D 90° Correct Answer Incorrect Answer

    Solution

    In △ CDE, tan  θ = CD/CE = (BD - BC)/CE  = (24 - 1.5)/ 22.5 = 22.5/22.5 tan  θ = 1 = tan 45 °   θ =  45 °
