In the image provided, you are given two parallel lines, \( m \parallel n \), and asked to find the values of \( x \) and \( y \).

The given angles are:
- \( (x + 19)^\circ \) (at the top right)
- \( (3y + 8)^\circ \) (at the bottom left)
- \( (2x + 1)^\circ \) (adjacent to the previous angle)

### Key Concept:
Since the lines \( m \) and \( n \) are parallel, several angle relationships apply. Specifically, alternate interior angles are congruent, and corresponding angles are congruent.

#### Step 1: Use the corresponding angles relationship.
The angle \( (x + 19)^\circ \) at the top is corresponding to \( (2x + 1)^\circ \) at the bottom. Since they are corresponding angles, they must be equal:
\[
x + 19 = 2x + 1
\]
Solve for \( x \):
\[
x + 19 = 2x + 1
\]
Subtract \( x \) from both sides:
\[
19 = x + 1
\]
Subtract 1 from both sides:
\[
x = 18
\]

#### Step 2: Use the alternate interior angles relationship.
The angle \( (3y + 8)^\circ \) is an alternate interior angle to \( (x + 19)^\circ \). Since alternate interior angles are equal:
\[
3y + 8 = x + 19
\]
Substitute \( x = 18 \) from the previous step:
\[
3y + 8 = 18 + 19
\]
\[
3y + 8 = 37
\]
Solve for \( y \):
\[
3y = 37 - 8
\]
\[
3y = 29
\]
\[
y = \frac{29}{3} = 9.67
\]

### Final Answer:
- \( x = 18 \)
- \( y \approx 9.67 \)
