Find analytically the sum or resultant of the following displacements:
A= 10m Northwest , B= 20m 30 degree north of east and C = 35m due Souh

Henry
All angles are measured CCW from +xaxis:
Fr = 10m[135o] + 20m[30o] + 35m[270o].
Fr = (7.07+7.07i) + (17.32+10i) + (035i),
Combine liketerms and convert to polar form:
10.25  17.93i = 20.7m[60o] = 20.7m[60o] S. of E.
