From the data below with AU 0.015 ft BU 0.011 ft CU

From the data below with AU 0.015 ft BU 0.011 ft CU 0.012 ft being their errors. Use weighted least square adjustment to answer the following (a) What are the most probable values for the adjusted coordinates of station U? (b) What is the reference standard deviation of unit weight? (c) What are the estimated standard deviations of the adjusted coordinates? (d) Tabulate the adjusted distances, their residuals, and the standard deviations. AU 2828.83 ft = BU = 2031.55 ft the control coordinates of A, B, and C are: Station A B C x (ft) 1418.17 2434.53 3234.86 CU 2549.83 ft = y (ft) 4747.14 3504.91 2105.56
