Length of the shadow of a 15 meter high pole is `5sqrt3` meters at 8 O'clock in the moming. Then, what is the angle of elevation ofthe Sun rays with the ground at the time?

If the ratio of the height of a tower and the length of its shadow is sqrt(3):1 , then the angle of elevation of the sum had measure.

The shadow of a pole is sqrt(3) times longer the angle of elevation of sun is equal to

The length of the shadow of a vertical pole of height h , thrown by the suns rays at three different moments are h ,2ha n d3h . Find the sum of the angles of elevation of the rays at these three moments.

A 1.5 m tall boy is looking at the top of a temple which is 30 meter in height from a point at certain distance. The angle of elevation from his eye to the top of the crown of the temple increases from 30^(@) to 60^(@) as he walks towards the temple. Find the distance he walked towards the temple.

A tower stands vertically on the ground. From a point which is 15 meter away from the foot of the tower, the angle of elevation of the top of the tower is 45^(@) . What is the height of the tower?

A building is 200sqrt3 meters high. Find the angle of elevation if its top is 200 m away from its foot.

The top of a 15m high tower make an angle of elevation of 60^(@) with the bottom of an electronic pole and angle of elevation of 30^(@) with the top of the pole. What is the height of the electric pole?

A pole 5 m high is fixed on the top of a tower. The angle of elevation of the top of the pole observed from a point 'A' on the ground is 60^(@) and the angle of depression to the point 'A' from the top of the tower is 45^(@) . Find the height of the tower. (sqrt(3)=1.732)
