  1. Question 1

    Q1. The angle of elevation of the top 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 it, the angle of elevation is found to be 60°. The height of the tower is

    • A) 50√3 m
    • B) 86.6 m
    • C) 100 m
    • D) 40 m

    Answer: 86.6 m

    Explanation: Using the relation between the two angles of elevation, we derive the height of the tower.
