A tacheometer is set up at an intermediate point on a traverse course AB and the following observations are taken on a staff held vertically. Staff station Bearing Vertical angle Staff intercept Axial hair reading A 0.55 2.150 225° 30' 45° 30' (-)4° 24' (-)5° 12' 0.30 1.800 B The instrument is fitted with an anallatic lens and the multiplying constant is 100. The RL of A being given as 351.75 m, calculate the length of AB and RL of B.
