The angle of elevation of the top of a building from a point on the ground is 45°. If the height of the building is 50 m, find the distance between the point and the building.
Q1. The angle of elevation of the top of a building from a point on the ground is 45°. If the height of the building is 50 m, find the distance between the point and the building.
Answer: 50 m
Explanation: Using trigonometric ratio: tan(45°) = 50 / distance, so distance = 50 m since tan(45°) = 1.
