If the angle of elevation of a cloud from a point h metres above a lake is `alpha` and the angle of depression of its reflection in the take is `beta` , prove that the height of the cloud is `(h(tanbeta+t a nalpha))/(tanbeta-t a nalpha)`

If the angle of elevation of a cloud from a point h metres above a lake is alpha and the angle of depression of its reflection in the take is beta prove that the height of the cloud is h(tan beta+tan alpha)quad tan beta-tan alpha

If the angle of elevation of a cloud from a point h metre above the lake is alpha and the angle of depression of its reflection in the lake is beta , prove that the height of the cloud above the lake is (h(tan beta+tan alpha))/(tan beta- tan alpha)

If 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 reflexion in the lake is beta , prove that the height of the cloud is (h (tan beta + tan alpha))/(tan beta - tan alpha) metres.

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 :

If the angle of elevation of the cloud from a point hm above a lake is A and the angle of depression of its reflection in the lake is B prove that the height of the cloud is h(tan B+tan A)tan B-tan A
