2. The resultant of three concurrent forces is 90.00 lbs 34°N of W. If two of these three forces are A=17.89 Ibs 27°W of S, and B =36.00 lbs NW, a) what is the magnitude and direction of the third force C? (Ans. 57.85 Ibs, 44.76°N of W) b) Using the result in (a), find the magnitude and direction of the resultant vector 2A – 3B + C?
