(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two vectorsAandBhave precisely equal magnitudes. For the magnitude ofA+Bto be 65 times greater than the magnitude ofA-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!!
