A man standing on a cliff observes a boat at an angle of depression 30°. If the distance from the man to the boat is 50 m, find the height of the cliff.
Q1. A man standing on a cliff observes a boat at an angle of depression 30°. If the distance from the man to the boat is 50 m, find the height of the cliff.
Answer: 25 m
Explanation: Using trigonometric ratio for angle of depression, tan(30°) = height / 50*cos(30°), simplifying yields height = 25 m.
