Arithmetic Aptitude :: Height and Distance

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. respectively. If the lighthouse is 100 m high, the distance between the two ships is:

A man standing at a point P is watching the top of a tower, which makes an angle of elevation of 30Ã‚° with the man's eye. The man walks some distance towards the tower to watch its top and the angle of the elevation becomes 60Ã‚°. What is the distance between the base of the tower and the point P?
