Question

??

Answer 1

\[r=\sqrt{3^2+1^2}=\sqrt{10}\]

Answer 2

because in this example you are in quadran iv you can use
\[\theta=\tan^{-1}(\frac{b}{a})=\tan^{-1}(-\frac{1}{3})\]

Answer 3

was that 8 options to choose from?

Answer 4

i get
\[\theta=-18.43\] degress, add 360 degrees to get your answer

Answer 5

looks like option 4 if you round to the nearest degree because \(360-18.43=334.57\)
ick

Answer 6

360-18.43 is 341.57

Answer 7

so its option 6

Answer 8

no wait yeah 4
