! ♡ Have a great day :D

I think It's option B

Step-by-step explanation:

But I am not sure It's correct or not

I hope It's helpful

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

< 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
