Following observations were taken using a Tacheometer with staff held vertical. The additive and multiplying constants of the instrument are 0 and 100, respectively. The reduced level (RL) of the staff station R, in m, is _______________. (rounded off to two decimal places)
Instrument station P, Staff station Q: Staff readings 1.4, 2.7, 3.9; Vertical angle 7°; RL of Q = 102 m
Instrument station P, Staff station R: Staff readings 2.1, 2.8, 3.6; Vertical angle 5°
Instrument station P, Staff station Q: Staff readings 1.4, 2.7, 3.9; Vertical angle 7°; RL of Q = 102 m
Instrument station P, Staff station R: Staff readings 2.1, 2.8, 3.6; Vertical angle 5°
Correct : 84.68
