  1. Question 1

    Q1. The angle of elevation of the top of a vertical tower from a point A on the ground is 60°. From a point B, 20 m vertically above A, the angle of elevation is 45°. Find the height of the tower.

    • A) 30 + 10√3 m
    • B) 47.32 m
    • C) 20 + 20√3 m
    • D) 60 m

    Answer: 47.32 m

    Explanation: Relating the two observations using tangent, we solve for height = 47.32 m.
