Answer:

∠2 = 45°

Explanation:

Angles 1 and 2 are same-side interior angles where the transversal crosses parallel lines. That means they are supplementary angles.

∠1 +∠2 = 180° . . . . . supplementary angles total 180°

135° +∠2 = 180° . . . . substitute the given value

∠2 = 180° -135° . . . . subtract 135°

∠2 = 45°
