Answer:
Circumscribed circle: Around 80.95
Inscribed circle: Around 3.298
Step-by-step explanation:
Since C is a right angle, when the circle is circumscribed it will be an inscribed angle with a corresponding arc length of 2*90=180 degrees. This means that AB is the diameter of the circle. Since the cosine of an angle in a right triangle is equivalent to the length of the adjacent side divided by the length of the hypotenuse:
To find the area of the circumscribed circle:
To find the area of the inscribed circle, you need the length of AC, which you can find with the Pythagorean Theorem:
The area of the triangle is:
The semiperimeter of the triangle is:
The radius of the circle is therefore 
The area of the inscribed circle then is 
.

Answer:
Subtract 2x to bring it to the other side
Step-by-step explanation:
2x+5y=20
-2x. -2x
5y=-2x+20
From the given the option moved left 1 unit; reflected across the x axis is the correct.
what is function?
A function from a set X to a set Y in mathematics assigns each element of X exactly one element of Y. The set X is known as the function's domain, and the set Y is known as the function's codomain.
We have to describe the position of the function 
relative to the basic function 
.
Let the parent function is .
After shifting one unit right it becomes, 
.
After reflection in x axis it becomes, 
.
Hence, from the given the option moved left 1 unit; reflected across the x axis is the correct.

Answer:
1/2
Step-by-step explanation:
x + 9 = -15x = [1]
x - x + 9 = -15x -x = 1
9 - 1 = -16x
8 = 16x
8/16 = 16/16x
1/2 = x
