II.PROBLEM SOLVING. 1)A traverse line is being measured by theodolite and subtense bar.At one station,the theodolite's horizontal axis is 1.54m above the ground mark and the angle subtended by a 2-m subtense bar placed at the next station is 40'25". The subtense bar is 1.25m above the ground mark,and the vertical angle measured to it by the theodolite is (+)13°28'.Determine: a)the horizontal distance from the theodolite at A to the subtense bar at B bjthe vertical distance from the horizontal axis of the theodolite to the center of the bar c)the difference in elevation between the two ground stations
