The height of an EDM set up at station A is 1.415 m. The height of the reflector set up at station B is 1.124 m. The height of the theodolite at station A used to measure the vertical angle is 1.623 m. The height of the target at station B on which the vertical angle sight is taken is 1.175 m. The measured vertical angle is 5° 32' 45" (upward). The slope distance, after meteorological corrections, is 1537.248 m. Determine the horizontal distance between stations A and B.
