Quick check? Thank You for helping!
Use the formula v1*v2=v1v2cos theta to find the cosine of the angle between the two vectors (7,8) and (1,0).
I got cos theta=7/10.63. Is this correct? Thanks!

Best ResponseYou've already chosen the best response.0Cool, so from there I can take the inverse and get what theta is?

Best ResponseYou've already chosen the best response.0@Notsephirorth For this kind of calculations, it is best to leave the radical sqrt(113) because it is the exact value. 10.63 is only an approximation to sqrt(113).
