Question: How to convert 9-cis 300 degrees to rectangular coordinates?

I need an exact answer. I seem to have problems with this type of problem. Any help would be greatly appreciated! I wish I knew how. Thanks! I would love to see the steps so I hope to do it on my own next time! Thanks!

9 is the hypotenuse of a right triangle and the diagonal of the rectangle you’re looking for and so the height is 9sin (300) = 7794 x (W) is 9cos (300) = 4.5
