Field and survey geology and field training - Traversing

1-The bearing of a line AB is N 41° 36'E. The interior angle at B turned clockwise to the point C is 72° 36'. The bearing of the line BC is:   (i) N 31° 00'E (ii) N 119°53'W (iii) S 31° 00'E (iv) S 70° 12'W

2- Four interior angles of a five-sided polygon traverse were observed as; A=98° 33' 26'', B=111° 04' 37'', C=123° 43' 58'', and D=108° 34' 25''. The angle at E was not observed. If all observed angles are assumed to be correct, what is the value of angle E?

3-The bearing of AB is S 7° 12' W, and the bearing of BC is N 86° 13' W. Compute the deflection angle at B?
