9. AravindG

10. AravindG

|dw:1356107632149:dw| means pc =pd

11. KatieMO

ok

12. AravindG

now those were the observations

13. AravindG

lets look at angles angle c=angle d =x now 2x+34=180 2x=146 x=73

14. AravindG

that will be the obtuse angle

15. KatieMO

SOO, it is one of the ones with 73 in it...

16. KatieMO

THE FIRST ONE!?!?!!??!

17. AravindG

now as the lines are parallel angle BAC+angle ACD=180 ie acute angle+obtuse angle=180 acute angle=180-73=107 that will be option a 73,107 hope ur life's saved

18. KatieMO
