1. The problem statement, all variables and given/known data Let A= 3i - 6j and B= 4i - 5j. The direction of the vector C = A - B is at an angle of? 2. Relevant equations Magnitude= ( a^2 + b^2 ) ^1/2 Tan^-1 = b/a 3. The attempt at a solution A-B = 3-4 i -6--5j -1i -1j Tan^-1 = -1/-1 = 45 45+180 = 225 Is this correct?
