If the area of a larger rectangle is 3x(4x-6) and the area of a smaller rectangle is 5(2x+3), what is the difference in the areas of the rectangles? (use " to show exponent)

< 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
