here we have taken the angles as 45, 135 and 325
OM is the resultant of A and B vector. its magnitude is 100?2 unitfrom parallelogram law.
resultant of this OM and C is OQ vector from parallelogram law.magnitude is=?(OM2+OR2+2 OMXOR cos 135)
solve this to find the final resultant vector in magnitude and then its direction from parallelogram law.
