1. The problem statement, all variables and given/known data Two vectors are given by A = -2 i + 5 j and B = 2 i + 3 j Also find the angle between them 2. Relevant equations Not really sure but from my book i get A x B = -B x A 3. The attempt at a solution the answer is -16, but I'm confused I thought that it should look like -6 + 10 but why is it minus ten? How would I use this to find the angle?
