To solve for \( x \), we can use the property that angles formed by a transversal with parallel lines have specific relationships. In this case, it appears that angles \( 1 \) and \( 4 \) are corresponding angles.
Given that:
- \( m∠1 = 125° \)
- \( m∠4 = (x + 35)° \)
Since \( 1 \) and \( 4 \) are corresponding angles, they are equal:
\[ m∠1 = m∠4 \]
Thus, you can set up the equation:
\[ 125° = (x + 35)° \]
To isolate \( x \), you can subtract \( 35 \) from both sides of the equation:
\[ 125° - 35° = x \]
This simplifies to:
\[ 90° = x \]
So, the equation that solves for \( x \) is:
\[ 125 + 35 = x \]
Thus, the final answer in the given format would be:
\[ x° + 35° = 125° \]
