A traverse is being measure by theodolite and subtense bar. At one station, the theodolite axis is 1.36m above the ground mark and the horizontal angle subtended by a 2- meter subtense bar placed at the second station is 40'28". The subtense bar is 1.23m above the ground mark, and the vertical angle measured to it on the theodolite is +22°14'. Determine the horizontal distance between the two station marks.

A traverse is being measure by
theodolite and subtense bar. At one
station, the theodolite axis is 1.36m
above the ground mark and the
horizontal angle subtended by a 2-
meter subtense bar placed at the
second station is 40'28". The
subtense bar is 1.23m above the
ground mark, and the vertical angle
measured to it on the theodolite is
+22°14'. Determine the horizontal
distance between the two station
marks.
