Circle D is shown. Line segments E D, F D, and G D are radii. Angle E D F is 80 degrees and angle F D G is 35 degrees. Point H is on the other side of the circle. Which equation can be used to find the measure of Arc E H G? mArc E H G + 80 + 35 = 180 mArc E H G + 80 + 35 = 360 mArc E H G – 80 – 35 = 360 mArc E H G – 80 – 35 = 180
