A tacheometer is placed at a station A and readings on a staff held vertical upon a B.M. of RL =100.0 meter and at station B are 0.640, 2.200, 3.760 and 0.010, 2.120, 4.230 m respectively. The angle of depression of the telescope in the first case is 6° 19'and in the second case is 7° 42'. Find the horizontal distance from A to B and the RL of station B if the instrument has constants 100 and 0.5.
