Answer
$(3.10, 0.11)$
Work Step by Step
By definition we have $x=r\cdot \cos(\theta)$ and $y=r\cdot \sin(\theta)$.
Here, we are given $r=-3.1 \text{ and } \theta=182^\circ$.
Hence, after plugging these in:
$x=-3.1\cdot \cos(182^\circ)\approx3.10$
$y=-3.1\cdot \sin(182^\circ)\approx0.11$
The point has the coordinates $(3.10,0.11)$ in the rectangular coordinate system.
