So the radius (r coordinate) is sqrt(32) and the first theta coordinate is 315 degrees. add another 360 to that to get a second theta coordinate, with r constant at sqrt(32)

You got the sqrt of 32 because r=x^2+y^2. Since it is in the fourth quadrant that's why it is 315 degrees? The answer has to be between 0 and 360 degrees

I'm not sure how you got 315 degrees

@FutureMathProfessor Theta has to be between 0 and 360 degrees so that means there will be one r being positive and one r being negative in another pair of coordinates.

One pair you found (sqrt(32),315) The other one will have a negative r.

(4 , 315°), (4 , 135°) is this the answer?

it shoud say 4sqrt2

you can simplify sqrt(32) I'm sure. :) But yes.

But your r's are wrong and those pairs you gave.

Oh wait are you saying 4 or 4sqrt2?

4sqrt2 in the coordinate for the r
