Use the formula to solve for the given variable. Solve
i = Prt
for i, given that
P = $8000,

r = 9%,
and
t = 4 1/2 years.

8000 times 0.09 times 4.5

3240 is the amount of interest that will be gained

< 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
