1. The problem statement, all variables and given/known data Determine the vectors A-C, given the vectors A and C in Fig. 3-32. Vector A=44.0 at 28 degrees north of east and vector C=31.0 at 90 degrees south of east. 2. Relevant equations I don't know any. 3. The attempt at a solution 44.0-31.0=11.0, 28.0-90= -62 The answers are 64.6 and 53.1 degrees.
