Okay, here we have this:

Considering the provided figures, we are going to find the missing angles, so we obtain the following:

Remember that the sum of all the angles of any triangle is equal to 180°, so we have:

m∠A+m∠B+m∠C=180° ----> 30°+52°+m∠C=180° ----> m∠C=180°-82° -> m∠C=98°

m∠D+m∠E+m∠F=180° ----> 22°+50°+m∠F=180° --> 72°+m∠F=180° -> m∠F=108°
