Explanation:


\angle 3 and
\angle 16 are alternate exterior angles so they are equal to each other, which means


5x - 30 = 3x + 10 \Rightarrow x = 20

Solving for the measure of
\angle 16, we get


m\angle 16 = 5(20) - 30 = 70°

Since
\angle 12 and
\angle 16 are supplementary,


m\angle 12 = 180° - 70° = 110°
