Which value is in the domain of f(x)?
f(x) =
| 2x + 5,
1-2x +3,
-6 0 0
0
0
a) -7
b) -6
c) 4
d) 5

< 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
