The angular elevations of the top of a tower from two points in the same horizontal line with its foot and observed to be `theta and phi` respectively. Find the distance between the two points of observation, if the height of the tower is h.

Two men standing on either side of a tower 60m high observe the angle of elevation of the top of the tower is to be 45^@ and 60^@ respectively. Find the distance between two men.

If the angle of elevation of the top of a tower from two points distant a and b from the base and in the same straight line with it are comple mentary, then the height of the tower is____

From the two points on the same straight line with the foot of a tower the angles of elevation of the top of the tower are complementary. If the distance of the two points from the foot of the tower are 9 metre and 16 metre and the two points lie on the same side of the tower, then find the hegiht of the tower.

The angle of elevation of the top of a tower from a point O on the ground, which is 450 m away from the foot of the tower, is 40^(@) . Find the height of the tower.

The angle of elevation of the top of a tower standing on a horizontal plane from a point A is alpha. After walking a distance d towards the foot of the tower the angle of elevation is found to be beta. The height of the tower is____

A TV tower stands vertically on the side of a road. From a point on the other side directly opposite to the tower, the angle of elevation of the top of tower is 60^(@) From another point 1m away from this point, on the line joining this point to the foot of the tower, the angle of elevation of the top of the tower is 30^(@) . Find the height of the tower and the width ofthe road.

Two men on either side of a temple of 30 meter height observe its top at the angles of elevation 30^(@) and 60^(@) respectively. Find the distance between the two men.

If the angles of elevation of the top of a water from three collinear points, B and C, on a line leading to the foot of the tower, are 30^@, 45^@ and 60^@ respectively, then the ratio, AB:BC,is:
