Extracted text: The elevation of point C on the chimney shown in Figure 6.3 (from your textbook) is desired. Field angles and distances are observed. Station A has an elevation of 228.3510.03ft, and station B has an elevation of 222.8710.03. The instrument height, hiA, at station A is 5.5310.05ft and the instrument height, hiB, at station B is 5.5210.05ft. Zenith angles are read in the field. The other observations and their estimated errors are AB - 203.56 ft A = 43°15'21" B- 52°02'36" Note that distance AB and horizontal angles A and B are considered error-free z1 -85°22'30" + 15.6" 22 - 83°00'48" + 12.9" What are the elevation of the Chimney and the standard deviation in this elevation?
