Determine the domain of this relation (2,4), (1,3), (0,2), (1,1) a) d=(1,2) b) d=(0,1,2) c) d=(1,2,3) d) d=(1,2,3,4)

0,1,2

Step-by-step explanation:every x

< 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
