Reverse vector addition?

  1. Feb 27, 2009 #1
    The magnitude of vector A is 35.1 units and points in the direction 301° counterclockwise from the positive x-axis. Calculate the x-component of this vector.

    So...35.1=sqrt(vx^2 + vy^2)

    and 301°= vy/vx

    How do I do this?

    You just need trig. It's a right angled triangle. You know an angle and the hypotenuse, so what can you do to find the x component?
