The angle of depression from the top of a cliff to a boat is 45°. If the height of the cliff is 100 m, find the distance between the cliff and the boat.
Q1. The angle of depression from the top of a cliff to a boat is 45°. If the height of the cliff is 100 m, find the distance between the cliff and the boat.
Answer: 100 m
Explanation: Using trigonometric ratio: tan(45°) = 100 / distance, so distance = 100 m.
