A total of 60 raffle tickets were sold at a school fair Bethany has a 20% chance of wining how many tickets did she buy

12 tickets

Step-by-step explanation:

Turn the percentage into a decimal.

20% -> 0.2

Multiply.

60 * 0.2 = 12

Best of Luck!

< 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
