Answer:

arc AB = 90 degrees

x = 9

arc AD = 108 degrees

arc DC = 139 degrees

arc BC = 13 degrees

arc ADC = 247 degrees

Explanation:

12x+(17x-14)+(2x+5)+90 = 360

31x+81 = 360

31x = 279

x = 9

arc AD = 12(9) = 108 degrees

arc DC = 17(9)-14 = 139 degrees

arc BC = 2(9)+5 = 23 degrees

arc ADC = 108+139 = 247 degrees
