142.30 m 5 degrees South of East

Explanation:

75m north, = 75 [Cos (90) i + Sin(90)j]=75 j m
250m east, = 250 [Cos (0) i + Sin(0)j]=250 i m
125m at an angle of 30 degrees North of west = 125 [Cos (150) i + Sin(150) j]= -108.25i + 62.5j m
150m south. = 150 [Cos (270) i + Sin(270)j] = -150 j m

141.75 i - 12.5 j m
Displacement = 142.3 m
Angle: 5 degrees south of East
