To determine the height of a mobile tower, a theodolite was kept at two stations P and Q, 150 m apart, P being nearer to tower. The readings at the bench mark (of RL 555.055m) were 1.15 m from station P and 2.05 m from station Q. The vertical angles to the top of the tower were 17° 15 ô and 8° 40ô from station P and Q respectively. Find the horizontal distance and RL of top of the mobile tower.
