Nicole has $9 to spend on card. she finds friends with the same amount of money to split the cost of a set. one set costs $27. each friend gets the same number of card. how many cards does each friend get?

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

< 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
