B-17
Step-by-step explanation:
a right angle is 90° so if part of the angle is 73 we subtract 90-73 which equals 17
To solve this problem we are going to use the simple interest formula:
where
is the sum of the <span>interest and the principal
</span>
is the principal
is the interest rate in decimal form
is the time in years
<span>
We know for our problem that </span>
,
, and
. Now, let
represents our interest rate. To express the interest rate in decimal form, we are going to divide the rate by 100%:
.
Now that we have all the values we need, lets replace them in our simple interest formula to find the interest rate:
We can conclude that the interest rate of your cousin's loan was 8%.
