The transit used in a subtense tacheometry is set at station A with the height of 1.18m. A 2m subtense was set at station B with a height of 1.38m. The subtended angle was 2°12'38" while the vertical inclination of the transit is -14°26'10". Determine the horizontal and vertical distance between stations A and B. If station B has an elevation 57.31m, calculate the elevation of station A.
