Height of two towers are `20m` and `80`. Join foot of the tower to the top of other and vice versa. Find the height of intersection point from the horizontal plane.

From a point on the ground 40 m away from the foot of a tower, the angle of elevation of the top of the tower is 30^@ . The angle of elevation to the top of a water tank (On the top of the tower) is 45^@ . Find the height of the tower and the depth of the tank.

The angle of elevation of the top of a tower from a point A on the ground is 30^@ . On moving a distance of 20 metres towards the foot of the tower to a point B, the angle of elevation increases to 60^@ . Find the height of the tower and distance of the tower from the point A.

From the top of a tower 50 m high, the angle of depression of the top of a pole is 45^(@) and from the foot of the pole, the angle of elevation of the top of the tower is 60^(@) . Find the height of the pole if the pole and tower stand on the same plane.

Two vertical poles of height 10 m and 40 m stand apart on a horizontal plane. The height (in meters) of the point of intersection of the line joining the top of intersection of the lines joining the top of each pole to the foot of the other, from this horizontal plane is

The angle of elevation of the top of a chimney from the top of a tower is 60^(@) and the angle of depression of foot of the chimney from the top of the tower is 30^(@). If the height of the tower is 40m find the height of the chimney.

At a point 20 m away from the foot of a tower, the angle of elevation of the top of the tower is 30^@ The height of the tower is

80 m away from the foot of the tower, the angle of elevation of the top of the tower is 60^@ . What is the height (in metres) of the tower?

The angle of elevation of the top of a tower 30m high from the foot of another tower in the same plane is 60^(@) and the angle of elevation of the top the second tower from the foot of the first tower is 30^(@) . Find the distance between the two towers and also find the height of the other tower.
