The foot of a tower of height h m is in a direct line between two observers A and B. If the angles of elevation of the top of the tower as seen from from A and B are `alpha` and `beta` respectively and if AB=d m, then what is h/d equal to ?

The foot of a tower of height h m is in a direct line between two observers A and B. If the angles of elevationof the top of the tower as seenfrom and B are alpha and beta respectively and if AB = d m, then what is h/d equal to?

Two points A and B are on the ground and on opposite sides of a tower. A is closer to the foot of tower by 42 m than B. If the angles of elevation ofthe top of the tower, as observed from A and B are 60∘ and 45∘, respectively. then the height of the tower is closest to:

From the top and bottom of a building of height h metres, the angles of elevation of the top of a tower are alpha and beta respectively. Then the height of the tower is :

The angles of elevation of the top of a tower at the top and the foot of a pole of height 10 m are 30^@and 60^@ respectively. The height of the tower is

The angles of elevation of the top of a tower at the top and the foot of a pole of height 10m are 30^(@) and 60^(@) respectively.The height of the tower is

If the angle of elevation of the top of a tower from a distance of 100m from its foot is 60^(@) , the height of the tower is

The angle of elevation of the top of a tower at a point A due south of the tower is alpha and at beta due east of the tower is beta . If AB=d, then height of the tower is

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
