They can be up to 180 degrees

hint: since the angles are supplementary, then we can write this: \[\huge 7x + 33 + 70 = 180\]

how do we find which one it is

after a simplification, I get: \[\Large \begin{gathered} 7x + 103 = 180 \hfill \\ 7x = 180 - 103 \hfill \\ 7x = 77 \hfill \\ \end{gathered} \] please divide both sides by \(7\), what do you get?
