Answer: We are goinf to sovle triangle Number-03:

[tex]m\angle Q=?[/tex]

We know that the sum of angles in a triangle is 180 degrees, therefore we can do the following:

[tex]\begin{gathered} m\angle Q+30+31=180^{\circ} \\ \therefore\rightarrow \\ m\angle Q=180^{\circ}-61=119^{\circ} \\ \therefore\rightarrow \\ m\angle Q=119^{\circ} \end{gathered}[/tex]

This is the unknown angle that we were interested in.!
