In the image, the problem is asking for the measures of two angles, represented algebraically as:

- The larger angle is given by the expression \( (21x + 19)^\circ \)
- The smaller angle is given by the expression \( (14x + 4)^\circ \)

The two angles appear to be **linear pair angles**, meaning they are adjacent and their measures add up to \( 180^\circ \) since a linear pair always forms a straight line.

### Let's solve for \( x \):

1. The sum of the two angles must be \( 180^\circ \). So, we can set up the equation:
   \[
   (21x + 19) + (14x + 4) = 180
   \]

2. Combine like terms:
   \[
   21x + 14x + 19 + 4 = 180
   \]
   \[
   35x + 23 = 180
   \]

3. Subtract 23 from both sides:
   \[
   35x = 157
   \]

4. Divide by 35:
   \[
   x = \frac{157}{35} \approx 4.49
   \]

### Now, substitute \( x \) back into the expressions for the angles:

- Larger angle: 
  \[
  21x + 19 = 21(4.49) + 19 = 94.29 + 19 = 113.29^\circ
  \]
  
- Smaller angle: 
  \[
  14x + 4 = 14(4.49) + 4 = 62.86 + 4 = 66.86^\circ
  \]

### Conclusion:
- The larger angle measures approximately **113.29°**.
- The smaller angle measures approximately **66.86°**.
