Setting the coordinate system: positive x points to the east and positive y points to the north. This can be solved by vector addition.
A = <40cos(45), 40sin(45)>
B = <-60cos(60), 60sin(60)>
C = <0, -50>
R = A + B + C = <-1.72, 80.25>
The displacement that needs to return him is by the vector -R.
Therefore, <1.72, -80.25>
