To solve this problem, let’s analyze the information provided in the image and equations for each angle. The given angles and their expressions are:

1. **\( m\angle CAM = (2x - 10)^\circ \)**
2. **\( m\angle BFM = (3x - 35)^\circ \)**
3. **\( m\angle FMJ = (2.5x - 17.5)^\circ \)**
4. **\( m\angle FAE = (x + 5)^\circ \)**
5. **\( m\angle FMB = x^\circ \)**

### Steps to Find the Unknowns

#### 1. Find \( m\angle FBE \):
   - Since \( \overline{AE} \parallel \overline{DJ} \) and \( \overline{CH} \parallel \overline{BM} \), the given quadrilateral is a **trapezoid**.
   - \( m\angle CAM \) and \( m\angle BFM \) form **alternate interior angles** with line segment \( \overline{AF} \) acting as a transversal.
   - Therefore, \( m\angle CAM = m\angle BFM \).
   
   Set up the equation:
   \[
   2x - 10 = 3x - 35
   \]
   Solving for \( x \):
   \[
   35 - 10 = x
   \]
   \[
   x = 25
   \]

#### 2. Substitute \( x = 25 \) to find the angle measures:
   - **\( m\angle CAM = 2(25) - 10 = 50 - 10 = 40^\circ \)**
   - **\( m\angle BFM = 3(25) - 35 = 75 - 35 = 40^\circ \)**

   Since these angles are equal, we have consistency.

#### 3. Find \( m\angle FBE \):
   Since \( \overline{BF} \parallel \overline{CE} \) and \( \overline{AF} \) is a transversal:
   - **\( m\angle FBE = m\angle CAM = 40^\circ \)**

#### 4. Find \( m\angle AEB \):
   \( \overline{AF} \parallel \overline{DJ} \), making \( \angle AEB \) equal to \( \angle FAE \):
   \[
   m\angle FAE = (x + 5) = 25 + 5 = 30^\circ
   \]

#### 5. Find \( m\angle JHD \):
   With parallel lines, we use \( m\angle FMJ \) and the calculation for \( x \):
   \[
   m\angle FMJ = 2.5(25) - 17.5 = 62.5 - 17.5 = 45^\circ
   \]
   As the angles \( \angle JHD \) will be equal by symmetry (alternate interior angle).

#### 6. Find \( m\angle C \):
   \( \overline{CH} \parallel \overline{BM} \), thus \( m\angle C = m\angle FMB \):
   \[
   m\angle FMB = x = 25^\circ
   \]

### Final Angle Measures
1. \( m\angle FBE = 40^\circ \)
2. \( m\angle AEB = 30^\circ \)
3. \( m\angle JHD = 45^\circ \)
4. \( m\angle C = 25^\circ \)

Let me know if you want more detailed explanations on each step.
