Question

An aeroplane at an altitude of 1500 metres finds that two ships are sailing towards it in the same direction. The angles of depression as observed from the aeroplane are 45° and 30° respectively. Find the distance between the two ships.

Answer 1

Let D is the aeroplane A and B are two ships.

Given : CD = 1500 m, ∠EDA = 30°, ∠EDB = 45°

In Δ DBC 

Thus, distance between two ships = 1095 m.
