Answer:

the point is in Quadrant 4 and the best match in the options is;

Point D

Step-by-step explanation:

Given the polar coordinates;


(-2,(5\pi)/(6))

To simplify, let us convert it to rectangular coordinates;


(r,\theta)\rightarrow(r\cos \theta,r\sin \theta)

so, we have;


\begin{gathered} (-2,(5\pi)/(6))\rightarrow(-2\cos ((5\pi)/(6)),-2\sin ((5\pi)/(6))) \\ (-2,(5\pi)/(6))\rightarrow(\sqrt[]{3},-1) \end{gathered}

The rectangular coordinate of the given point is;


(\sqrt[]{3},-1)

Therefore, the point is in Quadrant 4 and the best match in the options is;

Point D
