Question 290281
Hint: if 'x' is the length of the short side, then 2x is the length of the hypotenuse. Use the pythagorean theorem to find that the long side is {{{x*sqrt(3)}}} units long. So in this case, {{{2x=10}}}. Solve this for 'x' and plug the solution into {{{x*sqrt(3)}}} to find the length of the longer leg.
