I need help setting up the problem again >.< Since I don't know what arc AB is
Again..... realize that ALL of the arc angles add up to 360 degrees
12x + 17x-14 + 2x+5 + AB = 360 AB is labelled as a right angle , so it equals 90 degrees
12x + 17x-14 + 2x+5 + 90 = 360........... There ya go !
OK
12x+17x+2x - 14+5+90 = 360
31x = 279
x=9
