  1. Question 1

    Q1. The angle of elevation of the top of a tower from a point A on the ground is 30°. On moving a distance of 20 m towards the foot of the tower to a point B, the angle of elevation increases to 60°. The height of the tower is

    • A) 10√3 m
    • B) 20√3 m
    • C) 17.32 m
    • D) 30 m

    Answer: 17.32 m

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