Abby bought 3 sweaters that each cost the same amount and 1 skirt that cost $15. The items she bought cost a total of $90 before tax was added. Determine which equation could be used to find, x, the cost of each sweater.

< 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
