PROBLEM 2: A traverse line AB is being measured by theodolite and subtense bar. At station A, the horizontal axis of the theodolite is 1.48m above the ground mark and the horizontal angle subtended by a 2-meter subtense bar set up at station B is 42'18". The subtense bar is 1.22 m above the ground mark and the vertical angle measured to it on the theodplite is +13°56'. Determine the length of the line AB and the difference in elevation between the two ground station marks.
