300$^{\circ}$ 240$^{\circ}$
1) $\sin$$\theta = -\frac{\sqrt 3}{2} 2) Since \sin$$\theta$ is negative, $\theta$ lies in either 3rd or 4th quadrant. 3)The reference angle is 60 $^{\circ}$ since absolute value of the sin $\theta$ is 60$^{\circ}$ 4)The angle in quadrant 3 is 180$^{\circ}$ + 60$^{\circ}$ =240$^{\circ}$ 5)The angle in quadrant 4 is 360$^{\circ}$ - 60$^{\circ}$ =300$^{\circ}$
