Answer:
lines l and n are parallel
Step-by-step explanation:
Look at line q. It is a transversal to lines l and n.
m<4 = 112 and m<16 = 68.
m<4 + m< 16 = 112 + 68 = 180
Angles 4 and 16 are supplementary.
Angles 4 and 16 are same side interior angles of lines l and n and the transversal q.
Theorem:
If two lines are intersected by a transversal, such that same side interior angles are supplementary, then the two lines are parallel.
Answer: lines l and n are parallel (is that choice D.?)
