## Homework Statement

Find the scalar product of the 2 vectors.

Vector A is north of east at 70 degrees with a magnitude of 3.60m

Vector B is south of west at 30 degrees with a magnitude of 2.40m

## Homework Equations

ABcosx

## The Attempt at a Solution

I did dot product using the formula, 3.60x2.40xcos(-100) and got the wrong answer.. The answer is 13.00. What the hell did I do wrong? I did as the formula said I should do and failed. I don't get it??
