A tree cause a shadow 4 m long on the ground, when the angle of elevation of sun is 45^o. The height of the tree is

When the angle of elevation of the sun is 30^o, the length of the shadow caused by 50 m high building is

The length of shadow of a tower 50 m high at the time of the angle of elevation 45^o is.

The measure of angle of elevation of the top of a 75 √3  m   high tower from a point at a distance of 75 m from the foot of tower in a horizontal place is.

In ΔABC, , SinA  = 1/2  if BC = 6 cm, then AC is.

The length of the shadow of a tree 7 m, when the sun's elevation is 45^o is.

A ladder of 10 m length touches a wall at a high of 5m. The angle θ made by it with the horizontal is.

The ratio of height of a tower and the length of its shadow on the ground is √3   :  1. Then the angle of elevation of sun is

If a pole of height of 6 m cause a shadow 2√3 m long on the ground. Then the sun's elevation is.

Ratio of sides of right triangle with angle measures 30^o, 60^o, and 90^o is
