Step-by-step explanation:

<1+90=180

<1=90

<1+<2+<3=180

90+<2+<3=180

<2+<3=90

Using the same method as above ^ to find <1, we can use that to find <3+<4.

<3+<4=90

<3+35=90

<3=55

<1+<2+<3=180

90+<2+55=180

<2=35

Since the alternate exterior angles theorem works here, it means m and n are parralel.

Hope this helps, I am sorry if it does not, I can help further otherwise... =)
