Based on the information you provided, it looks like we are dealing with two parallel lines \( l \) and \( m \), and a transversal line \( n \) that intersects them at angles \( x° \) and \( 117° \).

When two parallel lines are intersected by a transversal, several angle relationships are formed. The angle formed on the same side of the transversal (which is the angle \( x \) and \( 117°\)) are supplementary angles, which means they add up to \( 180° \).

Thus, we can set up the equation:

\[
x + 117° = 180°
\]

To find \( x \), we will subtract \( 117° \) from \( 180° \):

\[
x = 180° - 117°
\]

Now, performing the subtraction:

\[
x = 63°
\]

Thus, the value of \( x \) is

\[
\boxed{63}
\] degrees.
