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 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

The angle of elevation of a stationary cloud from a point h meter above a lake is 15^(@) and angle of depression of its reflection in the lake is beta . Prove that height of the cloud above the lake is (h(tanbeta+tanalpha))/(tanbeta-tanalpha) .

If the angle of elevation of a cloud from a foot 4 meters above a lake is beta and the angle of depression of its reflection in the lake is alpha then the height is

If the angle of elevation of a cloud from a point h metres above lake is alpha and the angle of depression of its reflection in the lake be beta , prove that the distance of the cloud from the point of observation is (2 h sec alpha)/(tan beta - tan alpha)

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