Lines b and c are parallel.

Horizontal and parallel lines b and c are cut by transversal a. Where line b intersects line a, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 1, 2, (18 x + 4) degrees, (7 x + 1) degrees. Where line c intersects line a, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 5, 6, 8, 7.
What is the measure of Angle2?

mAngle2 = 31°
mAngle2 = 50°
mAngle2 = 120°
mAngle2 = 130°

Answer: 50°

Reason: At the intersection on line b the angles (18x + 4)° and (7x + 1)° are a linear pair, so
(18x + 4) + (7x + 1) = 180
25x + 5 = 180 → 25x = 175 → x = 7.

Then Angle 2 equals 7x + 1 = 7(7) + 1 = 50°.
