Special right triangles (45 45 90)

[d1ner]

Hi,
I was told to solve this on my study website and I'm having a hard time understanding the formula and what to do to find the legs of this 45-45-90 triangle. I understand the 30 60 90 triangle, but this seems to be different. What should I do?
Many thanks!

Can you solve \(\displaystyle 2x^2=(4\sqrt2)^2~?\)
