Question

PLEASE Determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°.

(5 square root of 2, 315°), (-5 square root of 2, 135°)
(5 square root of 2, 45°), (-5 square root of 2, 225°)
(5 square root of 2, 135°), (-5 square root of 2, 315°)
(5 square root of 2, 225°), (-5 square root of 2, 45°)

Answer 1

Hint the point is in the 4th quadrant

Answer 2

I'm not sure what you mean. I have never worked with this kind of problem before..
