Answer 3

I think the answer is the last one

Answer 4

\(\large x = r\cos \theta\)

\(\large y = r\sin\theta\)

Answer 5

So would it be the last one?

Answer 6

This is what it looks like

Answer 7

\(\large x = r\cos \theta = -7*\cos(5 \pi / 3) = \frac{-7}{2}\)

Answer 8

and then after that comes the 7sqrt3/2 right? :)

Answer 9

\(\large y = r\sin \theta = -7*\sin(5 \pi / 3) = \frac{7\sqrt{3}}{2}\)
