Find the length of side x in simplest radical form with a rational denominator.

Answer:
[tex]\frac{11\sqrt{2}}{2}}[/tex] or 5.5√2
Step-by-step explanation:
We can see that this is a 45-45-90 triangle
refer to the image below to see what that means
we can see that (in the image) 11=x√2
which means that x= 11/√2
to rationalize this fraction we mulitply both sides by √2 to get
[tex]\frac{11\sqrt{2}}{2}}[/tex] or 5.5√2
