A ladder of 20 mt long reaches a point 20 mt below the top of a flag staff. If the angle of elevation of the top of the flag staff at the foot of the ladder is 60 ^(@) then the height of the flag staff is

From a point P on the ground the angle of elevation of a 10m tall building is 30^@ . A flag is hoisted at the top of the building and the angle of elevation of the top of the flag-staff from P is 45^@ . Find the length of the flag-staff and the distance of the building from the point P . (Take sqrt(3)=1. 732) .

A ladder 13m long is leaned against the wall. The ladder reaches the wall to a height of 12 m. Find the distance between the wall and the foot of the ladder.

A flag-staff stands on the top of a 5 m high tower. From a point on the ground, the angle of elevation of the top of the flag-staff is 60^@ and from the same point, the angle of elevation of the top of the tower is 45^@ . Find the height of the flag-staff.

On a horizontal plane there is a vertical tower with a flag on the top of the tower. At a point 9 metres away from the foot of the tower the angle of elevation of the top and bottom of the flag pole are 60^@ and 30^@ respectively. Find the height of the tower and flag pole mounted on it.
