Problem 9 The azimuth of a line was determined by observing the altitude of a star from the western hemisphere on Aug. 19, 2006. The line is located in an area with a latitude of 48°15'24". The star was observed to have a zenith angle of 32°44'56", declination of 10°26'37", and horizontal reading of 113°16'07". Calculate the corrected azimuth of the line.
Please help with b, i & ii The slope distance between two stations A and B measured with EDM when corrected for meteorological conditions and instrument constants, is 113.893 m. The heights of the instrument and reflector are 1.739 m and 1.839 m, respectively, above the ground. To measure the vertical angle a theodolite was set up at A, 1.665 m above the ground and a target at B having height above the ground as 1.632 m. The measured angle above the horizontal was + 4°22′18″. Determine a. The horizontal length of the line AB. b. To what precision the slope angle be measured: i. if the relative precision of the reduced horizontal distance is to be 1/100000. ii. if the reduced horizontal distance is to have a standard error of ± 1.8 mm.
