$\frac{11\sqrt{2}}{2}}$ 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

$\frac{11\sqrt{2}}{2}}$ or 5.5√2
