Angle Relationships Practice Test

Quadrilateral $$MNPQ$$ is inscribed in a circle. If angle $$M = 3y + 15°$$, angle $$N = 2y + 25°$$, and angle $$P = 4y - 10°$$, what is the measure of angle $$Q$$?

Triangle $$ABC$$ has an exterior angle at vertex $$B$$ that measures $$142°$$. If angle $$A$$ is $$28°$$ more than angle $$C$$, what is the measure of angle $$A$$?
