5 2a) If f = (0,82, (6,10), (-2, 6), (-3,5)
and g=(0, 0), (-630),(2, 2), (3,-3)
fog by drawing mapping diagram

< 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
