**1. Homework Statement**

A vector A has a magnitude of 51.0 m and points in a direction 20.0° below the x axis. A second vector, B, has a magnitude of 70.0 m and points in a direction 43.0° above the x axis. Using the component method of vector addition, find the x- and y- components of the vector C.

**2. Homework Equations**

Vector A + Vector B = New Vector C

Cx = Ax + Bx

Cy = Ay + By

**3. The Attempt at a Solution**

I'm really not sure. In the book it says to put vector B at the head of vector A. I just drew each vector as a separate triangle and solved for Ax, Ay and so on. Like i said before, i just need to know what to do with the "20 degrees below the X-axis. Is it -20? 340? I've tried both and they came out wrong so help! Thanks again.
