yea after a while i figured it out. cos 300= 1/2

Im familiar with reference angles. I just didnt know to use them but since you mentioned it, what comes to mind is taking 60 degrees from 360 degrees. That leaves me with 300 degrees. From there, i don't know how to proceed.

Ok, thanks for the help. Making sure but there's nothing more to do to this problem, correct?

I'm not sure if the value of i by itself is 1 or whether or not to include it when I am finding the square root.
