The following TV Tower was built in 1988 and is loented in Pitampura, Delhi. It has an observation deck. Observe the picture given below:

The TV Tower stands vertically on the ground. From a point 'A' on the ground, the angle of elevation of top of the lower point "B") is 60. There is a point 'C' on the tower which is 78 m (approx.) above the ground.
The angle of elevation of the point C from point A is found to be 30.
Find the height of the tower and the distance of the tower from point A.
