Question

    From a point "A" on the ground, the angle of elevation

    to the top of a tower measuring 12 meters in height is 30°. Determine the horizontal distance between point "A" and the base of the tower.
    A 12 m Correct Answer Incorrect Answer
    B 4√3 m Correct Answer Incorrect Answer
    C 8 m Correct Answer Incorrect Answer
    D 12√3 m Correct Answer Incorrect Answer

    Solution

    Image
    Let BC = length of the tower = 12 metres
    In right triangle ABC;

    tan30 o  = (BC/AB)

    So, (1/√3) = (12/AB)

    So, AB = 12√3 m
