Answer:
An isosceles triangle is symmetrical and a right triangle has a 90 degree angle and not symmetrical so they are not the same.
Step-by-step explanation:
The circumference of the circle is equal to the perimeter of the triangle, then the area of the circle is 12 square units. Option D is correct.
<h3>What is a circle?</h3>
It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A triangle has sides that measure 2 units, 5 units, and 5.39 units.
The circumference of the circle is equal to the perimeter of the triangle. Then the radius of the circle will be
![2 \pi r = 5 + 2 +5.39\\\\r = 1.97](https://tex.z-dn.net/?f=2%20%5Cpi%20r%20%20%3D%20%205%20%2B%202%20%2B5.39%5C%5C%5C%5Cr%20%3D%201.97)
Then the area of the circle will be
![\rm Area \ of \ circle = \pi r^2\\\\Area \ of \ circle = \pi 1.97^2\\\\Area \ of \ circle = 12.21 \approx 12](https://tex.z-dn.net/?f=%5Crm%20Area%20%5C%20of%20%5C%20circle%20%20%3D%20%20%5Cpi%20r%5E2%5C%5C%5C%5CArea%20%5C%20of%20%5C%20circle%20%20%3D%20%20%5Cpi%201.97%5E2%5C%5C%5C%5CArea%20%5C%20of%20%5C%20circle%20%20%3D%20%2012.21%20%5Capprox%2012)
The area of the circle is 12 square units.

Answer:
x=20 and y=70/3
Step-by-step explanation:
We know triangle DEF is similar to triangle HJG. So:
- DE is similar to HJ
- EF is similar to JG
- FD is similar to GH.
We know:
- DE=9, which is similar to 15
- EF=14, which is similar to y
- FD=12, which is similar to x
The ratio of DE:HJ=EF:JG=FD:GH. We know DE:HJ=9:15=3:5, now we can find x and y:
- DE:HJ=9:15=3:5
- EF:JG=14:y=3:5, so y is 70/3 because 14=42/3 and 42/3:70/3=3:5 as 42=14•3 and 70=14•5
- FD:GH=12:x=3:5, so x is 20
