Given:


\begin{gathered} m\angle A=22\degree;m\angle B=50\degree \\ m\angle D=22\degree\text{ ; m}\angle E=50\degree \end{gathered}

In a triangle ABC,

Sum of the angles in a triangle is 180 degree


\begin{gathered} \angle A+\angle B+\angle C=180 \\ 22+50+\angle c=180 \\ \angle C=180-72 \\ \angle C=108 \end{gathered}

In a triangle DEF,


\begin{gathered} \angle D+\angle E+\angle F=180 \\ 22+50+\angle F=180 \\ 72+\angle F=180 \\ \angle F=180-72 \\ \angle F=108 \end{gathered}
