To solve for the missing angles in this problem, let's analyze the given angles and relationships between them in the triangle and adjacent lines.

### Step-by-Step Breakdown:

1. **Angle at \( J \) (MJK)**:
   - The angle \( \angle MJL \) is given as 132°, and since \( MJL \) is a straight line, the angle next to it, \( \angle KJL \), can be found by subtracting 132° from 180° (angles on a straight line sum to 180°):
   \[
   \angle KJL = 180^\circ - 132^\circ = 48^\circ.
   \]

2. **Angle at \( L \) (KLN)**:
   - Similarly, for the straight line at point \( L \), \( \angle KLN \) is supplementary to \( \angle MLN = 112^\circ \). Therefore, the angle \( \angle KLM \) is:
   \[
   \angle KLM = 180^\circ - 112^\circ = 68^\circ.
   \]

3. **Angle at \( K \)**:
   - To find \( \angle JKL \), the third angle in triangle \( JKL \), we use the fact that the angles in a triangle sum to 180°:
   \[
   \angle JKL + \angle KJL + \angle KLM = 180^\circ.
   \]
   Substituting the known values:
   \[
   \angle JKL + 48^\circ + 68^\circ = 180^\circ,
   \]
   \[
   \angle JKL = 180^\circ - 116^\circ = 64^\circ.
   \]

4. **Finding \( x \)**:
   - The angle at \( K \) is expressed as \( (2x + 4) \). From the previous calculation, we know that \( \angle JKL = 64^\circ \), so:
   \[
   2x + 4 = 64^\circ.
   \]
   Solving for \( x \):
   \[
   2x = 64^\circ - 4^\circ = 60^\circ,
   \]
   \[
   x = \frac{60}{2} = 30^\circ.
   \]

### Final Answers:
- \( \angle KJL = 48^\circ \),
- \( \angle KLM = 68^\circ \),
- \( \angle JKL = 64^\circ \),
- \( x = 30^\circ \).
