Which of these is another way to write the function ƒ(x)+16^x?
a) f(x)=4 x/4
b) f(x)=2^4x
c) f(x)=2 x/4
d) f(x)=4^4x

< 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
