I've done many other problems like this and understood them all but when it comes to 20 degrees below the x-axis it threw me off. I tried putting the angle to 340 degrees but that was incorrect. I know something has to be negative, i just can't keep guessing at getting it wrong. Hope someone can help!! 1. The problem statement, all variables and given/known data 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. Relevant 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.
