Answer:
Angle MNL=50°
Angle JNM=130°
Line JL =180° so you have to do 180-130 and that gives you the angle measure for angle MNL
Angle N is 130°. If angles are opposites like N and 130°, they are usually the same angle measure.
Parallel lines can change that, but there aren't any in this problem.
Good luck!
