11 A theodolite was set up near the middle of the points "P" and "Q". If the height of the instrument is 1.20 m. The rod is sighted at point "P", vertical angle = +24 degrees, rod reading = 1.3 m, and stadia interval = 1.4 m. Then the rod is sighted at point "Q", vertical angle = +23 degrees, rod reading = 1.6 m, and stadia interval = 1.1 m. Taking K = 100, and C = 0. c) Elevation of Point "P" from the base of the theodolite. 51.920 m 32.763 m 44.895 m 41.045 m 48.526 m None of the Choices 36.994 m
