1. **Given Values:**
- \( \angle JIK = 26^\circ \)
- \( \angle KIM = 48^\circ \)
- Length \( IM = 14 \) inches
- Length \( KM = 10 \) inches
2. **Required Measures:**
- Length \( JK \)
- Length \( JI \)
- Measure \( m \angle KME \)
- Measure \( m \angle JIM \)
- Measure \( m \angle EMI \)
3. **Explanation of the Diagram:**
- Points \( J, K, I, \) and \( M \) form the vertices of a parallelogram.
- Point \( E \) appears to be an intersection of diagonals within the parallelogram.
- Angles and side lengths needed for calculation are marked within the diagram.
4. **Calculation Steps:**
- **Step 1:** *Determine Length \( JK \):*
Since opposite sides of a parallelogram are equal:
\[ \text{JK} = \text{IM} = 14 \text{ inches} \]
- **Step 2:** *Determine Length \( JI \):*
Similarly,
\[ \text{JI} = \text{KM} = 10 \text{ inches} \]
- **Step 3:** *Measure \( m \angle KME \):*
As diagonals in parallelograms bisect each other and opposite angles are equal, calculate:
\[ \angle KME = \angle KIM = 48^\circ \]
- **Step 4:** *Measure \( m \angle JIM \):*
Angles around point \( I \) that include:
\[ \angle JIM = 180^\circ - \angle JIK = 180^\circ - 26^\circ = 154^\circ \]
- **Step 5:** *Measure \( m \angle EMI \):*
Opposite angles in parallelograms are equal:
