Step-by-step explanation:
a) The figure is drawn in the attachment
__
b) The side lengths of a 30-60-90 right triangle have the ratio ...
1 : √3 : 2
Multiplying these by 4 gives the side lengths of each triangle created by the diagonal. The base (short leg) is 4 units; the height (long leg) is 4√3 units.
__
c) The area is the product of base and height:
A = bh
A = 4(4√3) = 16√3 . . . . square units

Using simple interest, it is found that $13,872 was loaned at 9%.
<h3>Simple Interest</h3>The amount of money after t years in simple interest is modeled by:
In which:
- P is the initial amount.
- r is the interest rate, as a decimal.
The interest earned is:
A bank loaned out $14000, in two parts, hence:
Part of it at the rate of 9% per year and the rest at 17% per year, hence:
The interest received in one year totaled $2000, hence:
Then:
Isolating as a function of
, then we can replace on the equation for the first interest.
Then:
$13,872 was loaned at 9%.
