    Ok let's plot \((3,-3)\);|dw:1435770062478:dw| We know length is \(3\sqrt2\) (all choice has that length) So about angle...

    |dw:1435770186673:dw| Can you determine angle for green arrow one?

    Since 360 - 45 = 315, would that be the green angle?

    |dw:1435771341338:dw| the length of the side is \(3\sqrt 2\) right? and the direction of the side is positive, hence, \(3\sqrt 2, 315 \) is one of the answer.

    Fortunately, you have only 1 option which has that part. If the first part of the option is correct, so as the second one, right?

    Makes sense, but then comes me wondering how you got 45 degrees out of that angle. Was it guessing?
