Jayden bought a slice of pizza for $1.25, a box of popcorn for $0.75, and a drink for $0.60. if he paid with a 5-dollar bill, how much change should he get?

< 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
