A plane is flying at the height of 5000m above the sea level. At a particular point, it is exactly above a submarine floating 1200m below the sea level. When is the vertical distance between them?

Write opposites of the following : (e) 100 m above sea level

An observer on the top of a cliff 200 m above the sea level, observes the angles of depression of two ships on opposite sides of the cliff to be 45^(@) and 30^(@) respectively. Then the distance between the ships if the line joining the points to the base of the cliff

A kite is flying at a height of 60m above the ground. The string attached to the kite is temporarily tied to a point on the ground. The inclination of the string with the ground is 60^(@) . Find the length of the string, assuming that there is no slack in the string.

An aircraft is flying at a height of 3400 m above the ground . If the angle subtended at aground observation point by the aircraft positions 10.0 s apart is 30^(@) , what is the speed of the aircraft ?

As observed from the top of a 100 m high light house from the sea level the angle of depression of two ships are 30^(@) and 45^(@) . If one of the ship is exactly behind the other on the same side of the light house, find the distance between the two ships. (sqrt(3)=1.73) .
