From a point on the ground the angle of elevation of top of a tower is α. On moving 'a' meter towards the tower, the elevation changes to β. The height of the tower is:

the angle of elevation of the top of the tower standing on a Horizontal plane from a pont A is α and after walking distance d towards it the amgle of elevation is β the height of tower is

Angle of elevation measured for a tower erected over a building from a point of aninstrument located on the ground was 12° and 9° for the top and bottom of the towerrespectively. The height of the tower is 9 m. If the angle at depression of plinth level ofthe building from the same instrument is 4°, calculate the height of the building. (7Marks)

The angles of elevation of the top of a tower from two points on the same side of the tower are α and β (α >β). If the distance between the two points is 40m, find the height of the tower.

From a point P on a level ground, the angle of elevation of the top tower is 30deg. If the tower is 100 m high, the distance of point P from the foot of the tower is

From a point 375 meters away from the foot of a tower, the top of the tower is observed at an angle of elevation of 45deg, then the height (in meters) of the tower is?
