Answer
300° in the IV quadrant
Work Step by Step
1. 270-360 degrees in the fourth quadrant. Therefore 270$^{\circ}$$\leq$300$^{\circ}$$\leq$360$^{\circ}$ its in the fourth quadrant
2. Coterminal angles always in the same quadrant with original angle, because of full resolutions (2$\pi$)
300° + 360° = 660°
300° - 360° = -60°
