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
