The angle of elevation of the top of a building from a point on the ground is 60°. If the height of the building is 20√3 m, how far is the point from the building?
Q1. The angle of elevation of the top of a building from a point on the ground is 60°. If the height of the building is 20√3 m, how far is the point from the building?
Answer: 20 m
Explanation: tan(60°) = height / distance. So, √3 = 20√3 / distance. Thus, distance = 20 m.
