square a = 7

square b = 50

square c = 7

sqaure d = 6

7 x 56 = (7 x 50) + (7 + 6)

350 +  42 =  392

7 x 56 = 392

< 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
