Allie bought a 5 pound bag of trail mix. she gave 12 oz of trail mix to justin. then she put the rest of the trail mix to into small bags to use for snacks. if each bag contained 4 oz of trail mix, how many small bags of trail mix did allie make?

< 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
