The angles are pairwise equal: 1 and 3 are equal, and 2 and 4 are equal.
So, we have
[tex]m_1=m_3=134[/tex]
Also, we have
[tex]m_1+m_2+m_3+m_4 = 360 \iff 268+2m_2 = 360 \iff 2m_2=92 \iff m_2=46[/tex]
So, we have:
- Angles 1 and 3 are the same and they are both 134
- Angles 2 and 4 are the same and they are both 46
