From a point P on a level ground, the angle of elevation of the top of a tower is 30°. If the tower is 100 m high, the distance of point P from the foot of the tower is :_________?
Q1. From a point P on a level ground, the angle of elevation of the top of a tower is 30°. If the tower is 100 m high, the distance of point P from the foot of the tower is :_________?
Answer: 173 m
Explanation: tan 30° = 1/√3 = 100/d, so d = 100√3 ≈ 173 m.
