Admission to the state fair is $8. It costs an additional $1.50 to go on a ride. Jordan spent a total of $15.50 on admission and rides. How many rides did Jordan ride?

15.50-8=7.5

7.5/1.50=5

Jordan went on five rides

< 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
