The route followed by a hiker consists of three displacement vectors A, B, and C.
Vector A is along a measured trail and is 2200 m in a direction 23.7° north of east.
Vector B is not along a measured trail, but the hiker uses a compass and knows that the direction is 43.8° east of south.
Similarly, the direction of vector C is 34.4° north of west.
The hiker ends up back where she started, so the resultant displacement is zero, or A + B + C = 0.
Calculate the magnitude of vector B.
