This is a repost of a question I posted yesterday...
Can someone please help me with this problem?
Trapezoid HGFE is inscribed in a circle, with EF parallel to 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.
Thank you so much!!!
