As observed from the top of a 75 m high lighthouse from the sea-level, the angles ofdepression of two ships are 30° and 45°. If one ship is exactly behind the other on thesame side of the lighthouse, find the distance between the two ships

Let us take AB = 75m,

∠ACB = 45°,

∠EAD = 30°

BC =?, DC= ?
