An object is observed from three points `A, B,C` in the same horizontal line passing through the base of the object. The angle of elevation at `B` is twice and at `C` is thrice than that at `A`. If `AB=a, BC=b` prove that the height of the object is `h=(a/(2b))sqrt((a+b)(3b-a))`

A ballon is observed simultaneously from the 3 points A,B,C on a staight road dirctly beneath it. The angles elevation at B is twice that at A and the angular elevation on at C is thrice that at A. If AB = 20, BC = 40 then the height of the ballon is

A balloon is observed simultaneously from three points A, B and C on a straight road directly under it. The angular elevation at B is twice and at C is thrice that at A . If the distance between A and B is 200 metres and the distance between B and C is 100 metres, then find the height of balloon above the road.
