Problem 2 (10 points)

The angles at the stations of a closed traverse ABCDEFA were observed as given in a table below.

Adjust the angular error in the observations, if any, and calculate the bearings of the traverse lines

if the whole circle bearing of the line AB is N42°E. Assume uniform conditions at the time of

observation of each angle and that the angles were measured with the same precision.
