Answer:
x = 142
Explanation:
The angles shown are corresponding angles.
Corresponding angles are the angles in the matching corners formed by the intersecting line. (note that they must be on the same side of the transversal)
Corresponding angles are congruent when the transversal intersects parallel lines.
This means that "x" and the angle with the measure of 142 degrees are congruent meaning x = 142
