1. **State the problem:** Find two angles between 0° and 360° whose cosecant is -2.
2. **Recall the definition:** Cosecant is the reciprocal of sine, so
$$\csc(\theta) = \frac{1}{\sin(\theta)}$$
3. **Given:**
$$\csc(\theta) = -2$$
4. **Find sine:**
$$\sin(\theta) = \frac{1}{\csc(\theta)} = \frac{1}{-2} = -\frac{1}{2}$$
5. **Determine angles where sine is -1/2:**
Sine is negative in the third and fourth quadrants.
6. **Reference angle:**
$$\sin^{-1}\left(\frac{1}{2}\right) = 30^\circ$$
7. **Find angles:**
- Third quadrant: $$180^\circ + 30^\circ = 210^\circ$$
- Fourth quadrant: $$360^\circ - 30^\circ = 330^\circ$$
8. **Answer:** The two angles are $$210^\circ$$ and $$330^\circ$$.
These angles satisfy $$\csc(\theta) = -2$$ between 0° and 360°.
