(adsbygoogle = window.adsbygoogle || []).push({}); 1. Vector A has a magnitude of 3 m and makes an angle of 10o with the positive x axis. Vector B also has a magnitude of 10 m and is directed along the negative x axis. Enter your answers in distance then angle(in degrees).

Find A + B

Find A - B

2. R = sqrroot(Cx^2+Cy^2)

Cx = Ax+Bx

Cy = Ay+By

A*sin(theta)=x

B*sin(theta)=y

3. 3*sin10=.5209 = Ay; 3*cos10=2.954=Ax

basically, I don't know how to get By and Bx values from a vector that is following either axis. if I could get those, then I would become unstuck from this problem very quickly. any conceptual help would be appreciated.
