A theodolite instrument is setup on point B. The measured zenith angles for points B.M., 1 and 2 respectively were: To point B.M. = 15°; To point 1 = 105°, and To point 2 = 99°. The horizontal distances were measured and found to be: From point B to B.M. = 12.7 m; from B to point 1 = 15.2 m; and from point B to point 2 = 10.7 m. Given that B.M. (X,Y, Z) coordinates= (1000, 1000, 1000); the azimuth of line 2 and B.M. = 20°, and the measured clockwise horizontal angle 12 B.M. = 40° The reduced level of point 2 is : O a. 948.53 m b. 950.405 m
