A transit is set up at point B which is between A and C. The vertical angle observed towards A is known to be -20° and that of C is +12°. The horizontal distance between A and B is 642.80 m and that of B and C is 1032.40 m. The height of instrument is 1.5 m above B with A having an elevation of 146.32 m. Considering the effect of curvature and refraction correction. Compute the difference in elevation between A and B (in meters). (answer in 3 decimal places) Compute the difference in elevation between A and C (in meters). (answer in 3 decimal places) Compute the elevation of B (in meters). (answer in 3 decimal places)
