Answer:
j ║ l ║ m
Step-by-step explanation:
Angles 1 and 3 are "consecutive exterior angles", so are supplementary if lines j and m are parallel.
∠1 + ∠3 = 135° +45° = 180° . . . . so, angles 1 and 3 are supplementary
Lines j and m are parallel.
__
Angles 2 and 3 are corresponding, so would be congruent if line k were parallel to lines j, l, and m. Those angles are not congruent, so line k is not parallel to any of the other lines.
The parallel lines are j, l, m.
