1. The problem statement, all variables and given/known data Two vectors A and B have precisely equal magnitudes. For the magnitude of A + B to be 65 times greater than the magnitude of A - B, what must be the angle between them? 2. Relevant equations 3. The attempt at a solution I tried using the dot product and solving for the angle but i dont know if my math was right. I keep getting a relatively small angle which I know is around the right answer but its still off somehow. Please help!!
