Question

below are two parallel lines with a third line intersecting them.
x = \square ^\circ

Explanation:

Step1: Identify angle relationship

The given angles are same-side interior angles formed by a transversal cutting parallel lines, so they are supplementary (sum to $180^\circ$).

Step2: Set up equation

$x + 122 = 180$

Step3: Solve for $x$

$x = 180 - 122$

Answer:

$58$
