Problem 1 (2 points): An annuity pays out $4000 at the beginning of each year in perpetuity. If the interest is 5% compounded annually, find:
a/ The present value of the whole annuity;
b/ The present value of the annuity for payments received, starting from the end of
ws
30th year.

< 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
