answer these problems step by step

A field party is capable of making taping observations with a standard deviation of plusminus0.003 m per 30 m tape length. What standard deviation would be expected in a distance of 90 m taped by this party? Line AD is observed in three sections, AB, BC, and CD, with lengths and standard deviations as listed below. What is the total length AD and its standard deviation? AB=1086.23 plusminus 0.05 ft; BC= 569.08 plusminus 0.03 ft; CD= 863.19 plusminus 0.04 ft AB=325.808 plusminus 0.004 m; BC= 801.193 plusminus 0.008 m; CD= 751.843 plusminus 0.006 m Determine the weighted mean for the following angles: 101 degree 36'17", wt 2; 101 degree 36'26", wt 3; 1O1 degree 36'21", wt 1; 1O1 degree 36'23", wt 4 10 degree 14'07" plusminus 2"; 1O degree 14'10" plusminus 4"; 10 degree 14'12" plusminus 3" What is the area of a rectangular field and its estimated error for the following recorded values? 201.54 plusminus 0.04 ft by 108.87 plusminus 0.03 ft 333.67 plusminus 0.03 ft by 231.46 plusminus 0.01 ft Specifications for observing angles of an n-sided polygon limit the total angular misdosure to E. How accurately must each angle be observed for the following values of n and E? n = 8, E = 6" n = 12, E = 2" Adjust the angles of a triangle ABC for the following angular values and weights: A = 80 degree 14'04", wt = 2; B = 38 degree 37'47", wt = 1; C = 6l degree 07',58", wt = 3
