There were 81 cupcakes. one-ninth are strawberry and 1/3 are vanilla. the other cupcakes are all chocolate. how many chocolate cupcakes are there?

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

< 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
