Hello Arthur, With 79.28 SW
Angle A should be 169.28 degrees and not 100.83 degrees
 
ie. Angle CAB = 169.28 degrees.

Surendra,
I just realized my mistake. I was making 79 degrees with the x-axis when I should have been making 79 degrees with the y-axis. Directional degrees is with the vertical. Thank you for correcting me.
