Answer:
The side lengths cannot belong to a right triangle.
Step-by-step explanation:
This is a simple case of Pythagorean proof. If this triangle was a right triangle, 20^2 + 21^2 = 28^2. However, this is not the case. 20^2 + 21^2 = 841, which square root is 29.
If you forgot, the Pythagoren Theorem is: a^2 + b^2 = c^2.
Hope this helps!

Answer:
2
Step-by-step explanation:
A=r²
(19/6)=(285/360)r²
Divide both sides by pi, and they cancel out.
x is the radius, so replace r with x.
19/6=285/360x²
19/6÷285/360=x²
(19/6)·(360/285)=x²
4=x²
√4=x
2=x
