  1. Question 1

    Q1. The angle of elevation of a tower from a point on the ground is 30°. At a point on the horizontal line passing through the foot of the tower and 100 m nearer to the tower, the angle of elevation is found to be 60°. Find the height of the tower.

    • A) 50√3 m
    • B) 86.6 m
    • C) 100√3 m
    • D) 200 m

    Answer: 86.6 m

    Explanation: Using tangent for both angles, we get height = 86.6 m.
