Koch was attempting to create a "curve” that was nothing but line segments and angles. Do you think he succeeded? If the curve
is formed recursively for many stages, what would happen to its
length?

< 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
