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.
