1) convert each true bearing to quadrant :
a) 140 b) 094

2) convert each quadrant bearing to true bearing :
a) s50w b) n15w

1) Converting true bearing to quadrant:
   a) 140 degrees.
       Taking North as origin, it would be:
         E50S
       So, final answer for this part is E50S

   b) 94 degrees
       Taking North as origin position, it would be: E04S
       So, final answer for this part is E04S

2) Converting to true-bearing:
   a) S50W = from north, it would be: 180+ 50 = 230 degrees
       So, 230 degrees is the answer.

   b) N15W = from north, in anti-clock wise direction (direction in which we usually calculate) would be: 360-15 = 345
       So, 345 degrees is the answer.

Hope this helps!
