The monthly payment is $ 1892.392
<em><u>Solution:</u></em>
<em><u>The formula for compound interest, including principal sum, is:</u></em>

Where,
A = the future value of the investment
P = the principal investment amount
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested or borrowed for
From given,
p = 12500
t = 5 years

n = 12 ( compounded mothly )
<em><u>Substituting the values we get,</u></em>

<em><u>What will her monthly payment be?</u></em>

Thus monthly payment is $ 1892.392
8 times 8=64,
9 times 9 = 81,
10 times 10= 100,
Ratio of 2 complementary angles = 4:5
Let first angle be 4x
Let second angle be 5x
Sum of two complementary angles = 90
4x + 5x = 90
9x = 90
x = 90/9 = 10
First angle = 4x = 4*10 = 40
Second angle = 5x = 5*10 = 50
