To solve for \( x \) and \( y \) in the given figure with parallel lines \( l \parallel g \):

### Step 1: Analyze the Angles

Since \( l \parallel g \), the corresponding angles formed by the transversal lines are equal. In this case:
1. The angle labeled \( x^\circ \) and the angle marked as \( 75^\circ \) are corresponding angles, so \( x = 75 \).
2. The angle \( (5y - 10)^\circ \) and the angle marked as \( 75^\circ \) are also corresponding angles, so \( 5y - 10 = 75 \).

### Step 2: Solve for \( x \)

From our analysis:
\[
x = 75
\]

### Step 3: Solve for \( y \)

Using the equation \( 5y - 10 = 75 \):
1. Add 10 to both sides:
   \[
   5y = 85
   \]
2. Divide by 5:
   \[
   y = 17
   \]

### Summary of Solutions:
- \( x = 75 \)
- \( y = 17 \)
