A civil engineer desires to measure the height of a tower observing a vertical angle at A. He then moves 54 meters further towards the tower at B and observes another vertical angle which is twice that of the first. He again proceed to move further towards the tower, still on the same line at distance of 21 meters. The observed vertical angle of the tower at this point is three times that the first. Determine the height of the tower.
