PLEASE HELP ME WITH THIS MATH PROBLEM FOR 26 POINTS AND BRAINLIEST AND EXTRA POINTS IF YOU GET THE BRAINLIEST FIRST

The answer is  C [ the third choice]

Step-by-step explanation:

I'm not sure what the answer is so I'd either choose :

C.) n > 6/7 or

D.) n > - 6/7

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
