Answer :

sqrt{2} = [tex]\sqrt{2}[/tex]

Given that

DF is the hypotenuse, we have:

DF = x sqrt{2}

x is the length of each leg.

Since DF = 22, we can setup the equation:

22 = x sqrt{2}

To simplify, we rationalize the denominator:

x = 22/[tex]\sqrt{2}[/tex] * sqrt{2} / sqrt{2} = 22sqrt{2}/2 = 11sqrt{2}

Thus, the length of each leg is:

11[tex]\sqrt{2}[/tex]
