A stationary balloon is observed from three points A, B and C on the plane ground and is found point is `60^(@)`. If `angleABC=30^(@)` and AC = 5 meters, then the height of the balloon from the ground is

A stationary balloon is observed from three points A, B and C on the plane groundand is found that its angle of elevation from each point is 60^(@) . If angleABC=30^(@) and AC = 5 meters, then the height of the balloon from the ground is

A spherical balloon of radius 10 feet is in the open air. If angle of elevation of centre of the balloon from a point on the ground is 45^(@) and spherical balloon subtens on angle of 45^(@) on that point then how high is the centre of the balloon from the ground ?

If the angle of elevation of a baloon from two consecutive kilometre -stones along a road are 30^(@)and60^(@) respectively , then the height of the balloon above the ground will be

If the angles of elevation of a ballon from the two consecultive kilometre stones along a road are 30^@ and 60^@ respectively, then the height of the balloon above the ground will be

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.
