A telegraph post is bent at a point above the ground due to storm. Its top just meets the ground at a distance of `8sqrt3` metres from its foot and makes an angle of `30^@`. Calculate at what heigh the post is bent and what is the height of the post.

A vertical post of 126 dcm height was bent at some point above the ground and it just touched the ground making an angle of 30^(@) with the ground. Calculate at what height was the post bent and at what distance did it meet the ground from the foot of the post.

The upper part of a lamp-post is broken by strom and the top touches the ground at an angle of 30^@ and at a distance of 8sqrt3 meter from the foot of the post. What was the height of the post.

Two houses stand just on the opposite sides of a road of a village. A ladder that stands against the wall of the first house is at a distance of 6 metres from the house and makes an angle of 30^(@) with the horizontal line.But if the ladder stands against the wall of the second house keeping its foot at the same point, it makes an angle of 60^(@) with the horizontal line. (a) Find the length of the ladder. (b) Calculate the distance of the foot of the ladder from the foot of the wall of the second house. (c) Find the width of the road. Find the height where the top of the ladder is fixed against the wall of the second house.

A tower of height b subtends an angle at a point 0 on the ground level through the foot of the tower and at a distance a from the foot of the tower. A pole mounted on the top of the tower also subtends an equal angle at 0. The height of the pole is

A palm tree stands on the bank of a river. A post is fixed in the earth on the other bank just opposite to the palm tree. On moving 7sqrt(3) metres from the post along the bank, it is found that the tree makes an angle of 60^(@) at that point with respect to this bank. Find the width of the river.

A palm tree stands on the bank of a river. A post is fixed I the earth on the other bank just opposite to the palm tree. On moving 7sqrt3 metres from the post laong the bank, it is found the tree makes an angle of 60^2 at that point with respect to this bank. Find the width of the river.

A 1.5m tall boy stands at a distance of 3m from a lamp post and casts a shadow of 4.5m on the ground. Find the height of the lamp.

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 vertical post 15 m high is broken at a certain height and its upper part, not completely seperated, metres the ground at an angle of 30^(@) . Find the height at which the post is broken.
