the cost of 4 boxes of small paper clips and 9 boxes of large paper clips is $15.75. Eight boxes of small clips and 7 boxes of large ones cost $16.65. Find the cost of a box of each size of paper clips.

< 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
