If the figure below is rotated 180 degrees about the origin, the new location is a’(8, 0), b’(0, -6), c’(-8, 0), d’(0, 6).

should be :)

sorry if wrong but it should be

< 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
