Given the quadrilateral:
The sum of the internal angles of a quadrilateral is 360°:
[tex]\begin{gathered} 150\degree+145\degree+6k+7k=360\degree \\ \\ 295\degree+13k=360\degree \\ \\ 13k=65\degree \\ \\ \Rightarrow k=5\degree \end{gathered}[/tex]
Finally, the measures of the two angles are:
[tex]\begin{gathered} 6k=30\degree \\ 7k=35\degree \end{gathered}[/tex]
