Answer:
26 sq in.
Step-by-step explanation:
Let x = measure of one acute angle
3x - 2 = measure of other acute angle
Since the triangle is a right triangle, the sum of the measures of the acute angles is 90
x + 3x - 2 = 90
4x - 2 = 90
4x = 92
x = 23
90 - 23 = 67
The acute angles are 23° and 67°
Now, let a = length of side opposite the 23° angle
sin 23 = a/12
a = 12 sin 23
Let b = length of the side opposite the 67° angle
sin 67 = b/12
b = 12 sin 67
Area = 1/2ab = 1/2(12 sin 23°)(12 sin 67°)
= 25.90
26 sq in to the nearest inch
Wow! That is quite the problem.

Answer:
Exponential decay function; -0.94%
Step-by-step explanation:
We are given an exponential function and we are supposed to find whether the given function increases or decreases and also the percentage of increase or decrease.
Th given function is f(x) = 2060
Here x denotes the number of years.
At the start the value was 2060. In the next year it was multiplied by 0.9906.
This means that the value becomes 0.9906 times after each year.
Hence the value decreases by 0.0094 times its original value.
Converting to percentage it becomes 0.94% decrease after each year.
