Answer:
x = 12
Step-by-step explanation:
Using the Altitude- on- Hypotenuse theorem
The 2 triangles are similar to the outside triangle and to each other, that is
Δ RQT ~ ΔSRT
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
x² = 144 ( take the square root of both sides )
x = = 12

Answer: 4,676.96
Procedure:
The formula for compounded interest is:
Future value = investment * factor
Interests = future value - investment
Where r is the monthly rate, which you calculate as the % yearly rate divided by 12.
And n is the number of months which is equal to the number of years times 12.
These are the calculations:
Future value = 3080.43 *2.518 = 7,757.39
Interests = 7,757.39 - 3080.43 = 4,676.96
