Ivan earns 8 each time he walk his neighbors dog he already walked the dog 5 times how many more times does he need to walk the dog to earn enough money to buy a game that cost 88

< 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
