In each diagram, line x is parallel to line y, and line z intersects lines x and y.

Based on the diagrams, which statement is true about the value of a?

• The value of a is 53 because it is adjacent to an angle that is 53.

• The value of a is 37 because 90 - 53 = 37.

• The value of a is 127 because alternate, exterior angles are congruent.

• The value of a is 180 because 53 + 127 = 180.
