  1. Question 1

    Q1. A tower stands on the top of a hill. The angle of elevation of the top of the tower from a point on the ground is 60°. If the height of the tower is 20 m and the height of the hill is 10 m, find the distance of the point from the foot of the hill.

    • A) 30 / √3 m
    • B) 30 √3 m
    • C) 10 √3 m
    • D) 10 / √3 m

    Answer: 30 / √3 m

    Explanation: tan 60° = (20 + 10) / distance. So, distance = 30 / √3 m.
