The measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.
<h3>Right angle triangle</h3>
Right angle triangle are triangle that has one of its angles as 90 degrees. The angles formed can be found using trigonometric ratios.
Therefore,
tan x° = opposite / adjacent
tan x° = 5 / 12
tan x° = 0.41666666666
x = tan⁻¹ 0.41666666666
x = 22.6198649482
x = 22.62°
Therefore, the measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.

Answer:
The total ammount in the compound interest account is $73325.30
Step-by-step explanation:
The compound interest formula is given by:
A: Amount of money(Balance)
P: Principal(Initial deposit)
r: interest rate(as a decimal value)
n: number of times that interest is compounded per unit t
t: time the money is invested or borrowed for.
In our problem, we have that:
A = total amount
P = $9000
r = 0.12
n = 2(semiannually means twice a year)
t = 18
So:
The total ammount in the compound interest account is $73325.30
