Case Study 2 The following TV Tower was built in 1988 and is located 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 tower (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 from point A is found to be `30^@`.
Find the height of the tower and the distance of the tower from point A.
