F1 = 50 N at 38o = ( 50 cos38 + 50 sin38 ) N = ( 39.40 + 30.78 ) N
F2 = 220 N at 65o = ( 220 cos65 + 220 sin65 ) N = ( 92.98 + 199.39 ) N
F3 = 390 N at 215o = ( 390 cos215 + 390 sin215 ) N = ( -319.47 -223.69 ) N
resultant F1 + F2 + F3 = ( -187.09 + 6.48 ) N
magnitude of resultant = 187.203 N
direction = tan-1 [ 6.48 / ( -187.09 ) ] = 178o
Resultant is 187.203 N at 178o
