From the top of a cliff 60 m high, the angles of depression of two boats on the same side of the cliff and in line with its foot are 45° and 60°. Taking √3 = 1.732, what is the distance between the boats?
Correct answer B. 25.36 m
Explanation
Distances from the foot: 60/tan 45° = 60 m and 60/tan 60° = 20√3 = 34.64 m. Gap = 60 - 34.64 = 25.36 m.
