![### Quadrilateral WXYZ Analysis
The diagram shows quadrilateral \( WXYZ \).
1. **Side WX:** The expression for side WX is \( 7m + 4 \).
2. **Side XY:** The expression for side XY is \( 2n - 1 \).
3. **Side YZ:** The expression for side YZ is \( 9m \).
4. **Side WZ:** The expression for side WZ is \( n + 6 \).
Angles are also given:
- **\(\angle WXY\):** \( (5y + 13)^\circ \)
- **\(\angle XYZ\):** \( (6y - 8)^\circ \)
### Parallelogram Property
For \( WXYZ \) to be a parallelogram, opposite sides should be equal. Hence,
\[ WX = YZ \]
\[ XY = WZ \]
### Equation Formation
1. **Equating \( WX \) and \( YZ \):**
\[
7m + 4 = 9m
\]
Simplifying this:
\[
4 = 2m \implies m = 2
\]
2. **Equating \( XY \) and \( WZ \):**
\[
2n - 1 = n + 6
\]
Simplifying this:
\[
n - 1 = 6 \implies n = 7
\]
**So, the correct values are \( m = 2 \) and \( n = 7 \).**
### Multiple Choice Question
**What must the values of \( m \) and \( n \) be for \( WXYZ \) to be a parallelogram?**
- \( \mathbf{A}. \quad m = 4, \, n = 5 \)
- \( \mathbf{B}. \quad m = 2, \, n = 7 \)
- \( \mathbf{C}. \quad m = 18, \, n = 13 \)
- \( \mathbf{D}. \quad Not enough information \)
### Correct Answer
**B. \( m = 2, \, n = 7 \)**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb294f3d7-c37e-4d19-872e-5bb2e2baac27%2F5f18e3d8-3075-452d-8d6c-501701ae3d35%2Fp4n16d_processed.jpeg&w=3840&q=75)
