For the traverse of Problem 20.27, the grid azimuth of a line from A to a nearby

Question:

For the traverse of Problem 20.27, the grid azimuth of a line from A to a nearby azimuth mark was 10°07'59" and the clockwise angle measured at A from the azimuth mark to B, 213°32'06". The measured interior angles were A= 41°12'26", B = 38°32'50", and C= 100°14'53". Balance the angles and compute grid azimuths for the traverse lines.
