6. Ex. 1 Solve for x. 84° x x = 42 

7. Ex. 2 Solve for y. 202° y y = 79 

8. Case III: Vertex is INSIDE circle (not the center) ANGLE ARC

9. Ex. 3 Solve for x. X 93° 113° x = 103 

10. Ex. 4 Solve for x X 88  84  x = 100 

11. Ex. 5 QU is a diameter x Q D T U y z x = 15  y = 15  z = 95 

12. Ex. 6 Solve for x. 45  93  xºxº 89  x = 89

13. Case IV: Vertex is OUTSIDE circle ANGLE LARGE ARC small ARC ANGLE LARGE ARC

14. x Ex. 7 Solve for x. 65° 15° x = 25 

15. x Ex. 8 Solve for x. 27° 70° x = 16 

16. x Ex. 9 Solve for x. 260° x = 80 

17. Tune: If You’re Happy and You Know It If the vertex is ON the circle half the arc. If the vertex is INside the circle half the sum. But if the vertex is OUTside, then you’re in for a ride, cause it’s half of the difference anyway.
