a. EDG = EDF + FDG since FDG = 80, EDF = 80 and EDG = 160. ENG = 360 - EDG = 200. b. The formula for arc length is angle/360 (fraction of the circle) times circumference. since (80/360)*circumference = 7, circumference = 31.5. 31.5 * (200/360) = 17.5 c. FEG = 360-80 = 280, 31.5*(280/360) = arc length = 24.5
