### Using the Law of Sines to Solve a Triangle

**Problem Statement:**
Use the Law of Sines to solve (if possible) the triangle. If two solutions exist, find both. Round your answers to two decimal places. (If a triangle is not possible, enter IMPOSSIBLE in each corresponding answer blank.)

**Given:**
- Angle \( A = 120^\circ \)
- Side \( a = 124 \)
- Side \( b = 104 \)

**Find:**
- Angle \( B \) = ______ \( \circ \)
- Angle \( C \) = ______ \( \circ \)
- Side \( c \) = ______

**Solution:**
1. **Apply the Law of Sines** \( \left( \frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C} \right) \).

2. **Solve for Angle \( B \):**
\[ \sin B = \frac{b \cdot \sin A}{a} \]

3. **Determine Angle \( C \):**
\[ C = 180^\circ - A - B \]

4. **Calculate Side \( c \) Using the Law of Sines:**
\[ \frac{c}{\sin C} = \frac{a}{\sin A} \]
\[ c = a \cdot \frac{\sin C}{\sin A} \]

If multiple solutions exist, consider:
- The Ambiguous Case for angle B, where there can be two possible values for \( B \) (one acute and one obtuse) leading to two different triangles.

**Insert your derived values for \( B \), \( C \), and \( c \) accordingly. If no valid triangle is possible due to computational or geometric contradictions, indicate 'IMPOSSIBLE' in each corresponding answer blank.**

**Note:** 
Ensure you round your answers to two decimal places as per the instructions.
