The angle of elevation of a cloud from a point 60 m above the surface of the water of a lake is `30^@` and the angle of depression of its shadow in water of lake is `60^@`. Find the height of the cloud from the surface of water.

The angle of elevation of a cloud from a point 10 meters above the surface of a lake is 30^(@) and the angle of depression of its reflection from that point is 60^(@) . Then the height of the could above the lake is

If the angle of elevation of a cloud from a point 10 metres above a lake is 30^(@) and the angle of depression of its reflection in the lake is 60^(@) . Find the height of the cloud from the surface of lake.

The angle of elevation of a stationary cloud from a point 200 m above the lake is 30^(@) and the angle of depression of its reflection in the lake is found to be 60^(@) . Find the height of the cloud .

The angle of elevation of a cloud from a height h above the level of water in a lake is alpha and the angle of depressionof its image in the lake is beta . Find the height of the cloud above the surface of the lake:

The angle of elevation of cloud from a point 60 m above a lake is 30^(@) and the angle of depression of the reflection of cloud in the lake is 60^(@) . Find the height of the cloud .

If the angle of elevation of a cloud from a point 200m above a lake is 30^(@) and the angle of depression of its reflection in the lake is 60^(@) .Then the height of the cloud above the lake is :

The angle of elevation of a cloud from a point h meter above the surface of the lake is alpha , the angle of depression of its reflection in the lake is beta . Prove that height of the cloud from observation points is (2hsecalpha)/(tanbeta-tanalpha) .

The angle of elevation of a stationary cloud from a point 2500 feet above a lake is 30^@ and the angle of depression of its reflection in the lake is 45^@ .Find the height of cloud above the lake water surface .
