Converting to component form help.

Let A = (4.6 m, 20$$^{}o$$ south of east)

How do I write this in compnent form? I know if it were (4.6m, North) is would simply be (0,4.6), but otherwise, how would I calculate this?

To find the components, 20 degrees south of east is just 20 degrees below due east. Therefore, the x-component will be 4.6*cos(20) and the y-component will be 4.6*sin(20).

Great! Thanks!
