The problem appears to involve solving for \( x \) given the relationship between the angle measures. Specifically, you're given:

- \( m \angle VTN = 3 \) (although this might be a mistake; perhaps you meant \( 3^\circ \) instead of 3)
- Another angle is given as \( (3x + 7)^\circ \)

Given this, let me walk you through the steps to solve for \( x \):

1. **Identify the Type of Relationship**:
   If \( m \angle VTN = 3^\circ \) and is related to \( (3x + 7)^\circ \) by a geometric relationship (e.g., supplementary, complementary, or equal angles), we need to define that relationship.

2. **Set Up the Equation**:
   - **If \( \angle VTN \) and \( (3x + 7)^\circ \) are equal angles**:
     \[
     3^\circ = 3x + 7^\circ
     \]
     Simplify to find \( x \).

   - **If the angles are supplementary (add up to \( 180^\circ \))**:
     \[
     3^\circ + (3x + 7)^\circ = 180^\circ
     \]
     Simplify and solve for \( x \).

   - **If the angles are complementary (add up to \( 90^\circ \))**:
     \[
     3^\circ + (3x + 7)^\circ = 90^\circ
     \]
     Simplify and solve for \( x \).

3. **Solve the Equation**:
   Based on the relationships, let's solve these cases:

   - **Case 1: Equal Angles**:
     \[
     3^\circ = 3x + 7^\circ
     \]
     Subtract \( 7^\circ \) from both sides:
     \[
     -4^\circ = 3x
     \]
     Divide by 3:
     \[
     x = -\frac{4}{3} \quad \text{(not realistic in most angle problems)}
     \]

   - **Case 2: Supplementary Angles**:
     \[
     3^\circ + 3x + 7^\circ = 180^\circ
     \]
     Combine like terms:
     \[
     3x + 10^\circ = 180^\circ
     \]
     Subtract \( 10^\circ \) from both sides:
     \[
     3x = 170^\circ
     \]
     Divide by 3:
     \[
     x = \frac{170^\circ}{3} \approx 56.67^\circ
     \]

   - **Case 3: Complementary Angles**:
     \[
     3^\circ + 3x + 7^\circ = 90^\circ
     \]
     Combine like terms:
     \[
     3x + 10^\circ = 90^\circ
     \]
     Subtract \( 10^\circ \) from both sides:
     \[
     3x = 80^\circ
     \]
     Divide by 3:
     \[
     x = \frac{80^\circ}{3} \approx 26.67^\circ
     \]

4. **Conclusion**:
   Without knowing the exact relationship between the angles, one of these results will be correct. If you clarify the angle relationship (equal, supplementary, or complementary), I can confirm the correct value of \( x \).

Would you like more details on these steps, or is there another specific relationship I should consider? Here are some related questions:

1. What is the difference between complementary and supplementary angles?
2. How do you determine the value of an unknown angle in a triangle?
3. What methods can be used to verify the accuracy of calculated angles?
4. Can angles ever be negative in geometry problems?
5. How do vertically opposite angles relate to each other in intersecting lines?

**Tip:** Always double-check the relationships between angles before solving, as the type of relationship (complementary, supplementary, etc.) will significantly affect the solution.
