From the top of a 100m high cliff, the angles of depression of two boats are 30° and 60°. If the boats are in line with the observer, how far apart are they?
Q1. From the top of a 100m high cliff, the angles of depression of two boats are 30° and 60°. If the boats are in line with the observer, how far apart are they?
Answer: 115.47 m
Explanation: Using tan(30°) = 100 / x and tan(60°) = 100 / y, we find x and y. The distance between the boats is x - y.
