NAME Other Angles In Exercises 1-4 overline AB and overline CD are chords 1. If mA hat C = 85 and m overline DB = 73 , then m angle 1 = (85 + 13) / 2 = 79 2. If m overline AD =136| and m overline CB = 96 , then m angle 1 = 180 - 110 = 104 3. If and m overline AC = 78 , then m overline DB =\ SCORE For use after Section 9-6 DATE A D EX1 B C Exs. 1-4 2 tangents case. 9B = (x + A_{2})/2 280-80 5. If m overline FHG = 280 , then MLE= 200 4. If m angle 1 = 48 and m hat DB = 42 , then m hat AC = underline boxed 54 find n angle AEO first In Exercises 5-7 overline EF and overline EG are tangents. 6. If m overline FG = 96 , then mLE = 264-96/2=848 let MFHG =3W 7. If m angle E = 90 , then 5-7 n overline FHG = 27 ^ O H G In Exercises 8-10 overline IJ is a tangent. tangent secant case 8. If m hat JK = 120 and then 40 m angle I = (120 * 40)/2 m overline JL = 40 , 9. If and then (x - 55)/2 = 45 ^ 1 m hat JL = 55 , m angle I = 45 L K 10. If and then m overline JL = 10 m angle I = 50 m hat JK = 110 , 50 = 110/2 In Exercises 11-15 overline RP and overline RT are secants. J Exs. 8-10 2 secants case P 11. If m hat PT = 100 and then 12. If m hat PT = 130 and then LD AS m overline QS = 20 , m angle R = (10Delta - 20)/2 = m hat QS = 40 , 13. If m angle R = 25 and m overline QS = 25 , then m hat PT = 5 14. If m angle R = 40 and m hat PT = 130 , then SD 15. If m overline ST = 90 , m overline QS = 60 , and m overline Q overline P = 80 , then R 90/2 = (120 - x)/2 Exs. 11-15 130-60 2 Q S T In Exercises 16-19 tangent to the A 16. If and then m overline BH = 20 , m hat AG = 100 m angle C = (160 - E_{0})/2 = boxed 2 x 17. If and mBH 25, then m angle C = 25 B C H 18. If and mGE 25, then mLD = m hat EH = 95 G D 19. If and then mGE = 58 m angle D = 40 m overline EH = 138 , E Exs. 16-19 18. (95 * 25)/2 (x - 25)/2 = 26 54 = (78 + x)/2 * x 40 = (138 - x)/2 (x - 25)/2 = 25
