Match the statements
1. m< 2 = 122° and m< 3 = 58°
if corresponding angles are equal, then lines are parallel.
2. 3 and 5 are supplementary angles
exterior sides in opposite rays
3. m< 3 + m< 5 = 180°
given
4. 58° + m< 5 = 180°
second substitution
5. m< 5 = 122°
definition of supplementary angles
6. m< 2 = m5
first substitution
7. l || m
subtraction property of equality

Okay so from my understanding, this is either geometry or trig. i took both classes last year, and I don't quite remember everything so I'll answer these questions to the best of my understanding. 
1= exterior sides in opposite rays
2= given
3= supplementary angles
4= subtraction property
5= second substitution
6= first substitution
7= if corresponding lines are equal, then lines are parallel.

hope this helps you brother, have a good day dude!
