Rachel and sierra are selling boxes of fruit as a fundraiser. rachel has sold 9/10 boxes of fruit and sierra has sold 2 has sold 5/8 of her boxes. which girl has sold a greater fraction of her boxes of fruit? draw a model and explain

step-by-step explanation:

< 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
