If a man standing on a platform 3 m above the surface of a lake observes a cloud and its reflection in the lake, then the angle of elevation of the cloud is equal to the angle of depression of its reflection.

If a man standing on a platform 3 m above the surface of a lake observes a cloud and its reflection in the lake, then the angle of elevation of the cloud is equal to the angle of depression of its reflection.

A helicopter is in a stationary position at a certain height over the lake. At a point 200 m above the surface of the lake, the angle of elevation of the helicopter is 45^(@) . At the same time, the angle of depression of its reflection in the lake is 75^(@) . Calculate the height of the helicopter from the surface of the lake :

The angle of elevation of a cloud from a point h metre above a lake is theta The angle depression of its reflection in the lake is 45^(@) The height of the cloud is

The angle of elevation of a cloud from a point h metres above the surface of a lake is alpha and the angle of depression of its reflection in the lake is beta then the height is :

The angle of elevation of a cloud from a point h metre above a lake is theta .The angle depression of its reflection in the lake is 45^@ The height of the cloud is

The angle of elevation of a cloud from a point h metres above a lake is beta . The angle of depression of its reflection in the lake is 45^(@) . The height of location of the cloud from the lake is
