A traverse line AB is being measured by a theodolite and substense bar. At station A, the horizontal axis of the theodolite is 2.87m above the ground mark and the horizontal angle subtended by a 2-meter substense bar set up at a station B is 3°. The substense bar is 1.35m above the ground mark and the vertical angle measured to it on the theodolite is 21°. Determine the difference in elevation between the two ground station marks.
2. The subtended angle read on a 2-m long subtense bar using a theodolite is 0°34'39". After checking, the subtense bar is found to be 0.02 m short. Compute the horizontal distance from the theodolite to the point sighted.
