From the top of a 100 m high cliff, the angles of depression of two ships on the sea are 30° and 60°. If one ship is exactly behind the other on the same side of the cliff, find the distance between the ships.
Q1. From the top of a 100 m high cliff, the angles of depression of two ships on the sea are 30° and 60°. If one ship is exactly behind the other on the same side of the cliff, find the distance between the ships.
Answer: 115.47 m
Explanation: Using cotangents for the angles, we derive the distance = 115.47 m.
