6) Imagine that the size of your friend’s illusion was 30 pixels. How would you explain to your friend what that means? (Explain this conceptually, do not just indicate which numbers are used in the calculation)

< 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
