Answer #1

Forbearing of EA= 321 degrees 33 minutes (360 degrees- 38 degrees 27 minutes)

Back bearing of EA= 141 degrees 33 minutes (321 degrees 33 minutes- 180 degrees)

Given interior angle at A= 113 degrees 7 minutes

Forbearing of AB = 141 degrees 33 minutes + 113 degrees 7 minutes

= 254 degrees 40 minutes

Bearing of AB in decimal degrees= 254.666667

Direction in letters= S 74 degrees 40 minutes W
