Question

I NEED HELP!

Answer 1

divide the hypotenuse by \(\sqrt 2\)

Answer 2

both legs of that triangle are equal (since angles have to be equal)
solve for \(x\) via pythagoras
\[x^2+x^2=13^2\\
2x^2=13^2\\
x\sqrt2 = 13\] so
\[x=\frac{13}{\sqrt2}\]

Answer 3

then rationalize the denominator to get your answer
