Trapezoid $EFGH$ is inscribed in a circle, with $EF \parallel GH$. If arc $GH$ is $70$ degrees, arc $EH$ is $x^2 - 2x$ degrees, and arc $FG$ is $56 - 3x$ degrees, where $x > 0,$ find arc $EPF$, in degrees.

Arc EPF is 205 degrees.

Thank you!

I almost never look at questions with unnecessary $ signs. It shows me how lazy the asker is.
