+1855 Trapezoid $HGFE$ is inscribed in a circle, with $\overline{EF} \parallel \overline{GH}$. If arc $GH$ is $66$ degrees, arc $EH$ is $x^2 + 8x$ degrees, and arc $FG$ is $25 + 16x$ degrees, where $x > 0,$ find arc $EPF$, in degrees.
+1950 Let's note something really important.
We need to find what ∠EPF is.
However, let's read through the problem. It never actually identifies what Pis!
This means it's impossible to solve the problem as P is not defined.
Thanks! :)
