5) [Book problem 7.17] Course AB of a five-sided traverse runs due north. From the given balanced interior angles to the right (A - E as shown below), compute and tabulate the bearings and azimuths from north for each side of the traverse. A = 156°23'53", B = 53°36'08", C = 83°15'58", D = 153°52'00", and E = 92°52'01" (Hints: you are asked to compute the azimuths and bearings of a 5-sided polygon traverse, whose first course, AB, runs due north, and whose balanced interior angles to the right are given. Use the tabular method demonstrated in class.)

(Note: Assume units of feet for all distances.) NEEDED ANS: Using the compass (Bowditch) rule, adjust the departures and latitudes of the traverse in Problem 1 considering the length of Problem 2. If the coordinates of station A are X = 20,000 ft and Y = 15,000 ft, calculate the final adjusted angles at stations C.(The answer must be in the form of degree, minutes, seconds.
