    This is a pretty easy one, do you know the Pythagorean Theorem?

    Since it's isoceles, the two legs have the same length. Now you can use pythagorus: x^2+x^2 = 5^2, solve for x :)

    in other words, x * sqrt(2) = 5 solve for x

    OK but coming up with that is much more difficult than simply using Pythagorus
