Aprincipal of $1,000 is invested in an account paying an annual interest rate of 4% using the formula a=p(1+r/n) ^nt find the amount in the account after 2 years if the account is compounded annually

< 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
