An aeroplane at an altitude of 1200 metres finds that two ships are sailing towards it in the same direction. The angles of depression of the ships as observed from the aeroplane are `60^o` and `30^o` respectively. Find the distance between the two ships.

An aeroplane at an altitude of 1500 meters finds that two ships are selling towards it in the same direction. The angles of depression as observed from the aeroplane are 45^(@)and30^(@) respectively. Find the distance between the two ships.

Two ships are sailing in the sea on the two sides of a lighthouse. The angle of elevation of the top of the lighthouse is observed from the ships are 30° and 45° respectively. If the lighthouse is 100 m high, the distance between the two ships is:

Two men on either side of the cliff 80m high observes the angles of elevation of the top of the cliff to be 30o and 60o respectively. Find the distance between the two men.

Two ships are there in the sea on either side of a light house in such a way that the ships and the light house are in the same straight line. The angles of depression of two ships are observed from the top of the light house are 60^@ and 45^@ respectively. If the height of the light house is 200 m, find the distance between the two ships.
