Convert the complex number from rectangular form to polar form. z = -14 + 8i

now.... that angle is correct for that tangent value, however, let's take a peek at our a,b elements,  "a" is negative and "b" is positive, that means the x-coordinate is negative and the y-coordinate is positive, that means, the II quadrant, NOT the IV quadrant.

so, let's get the twin of -29.74°, but adding 180° to it, and we'll land at 150.26° or thereabouts, which is in the II quadrant, where our a,b point is at.
