Below are two parallel lines with a third line intersecting them

Answer:
x = 122°
Step-by-step explanation:
Two parallel lines with a third line intersecting them are called a transversal.
The two angles shown in the picture, x and 122° are alternate interior angles.
Alternate angles are a pair of angles that are on the inner side of each of the two lines but are on opposite sides of a transversal.
These are really similar to vertically opposite angles!
All alternate angles have the same value, thus x = 122°.
You can also see that alternate angles are like corresponding angles and vertically opposite angles combined!
