To find:
The length of i.
Solution:
We have, G=30° and H=29º.
Using angle sum property, we get
According to Law of sines,
Using Law of sines, we get
Multiply both sides by 0.8572.
Therefore, the length of i is about 530 inches.

T = time taken (in years)
Therefore, the interest on $3,000 at 9% simple interest for 4 years is:
I = $1080
Therefore, the amount she will pay back is:
$3000 + $1080 = $4080
