Divide the following polynomials, then place the answer in the proper location on the grid. write the answer in descending powers of x.
9x 2 - 18x - 7 ÷ (3x + 1)

< 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
