You can put this solution on YOUR website!

hypotenuse is y%2B2
one leg is y, the other leg is 4
use Pythagorean theorem to find y
%28y%2B2%29%5E2=y%5E2%2B4%5E2
y%5E2%2B4y%2B4=y%5E2%2B16
cross%28y%5E2%29%2B4y%2B4=cross%28y%5E2%29%2B16
4y%2B4=16
4y=16-4
4y=12
highlight%28y=3%29=> your answer

so, hypotenuse is y%2B2=5, one leg is y=3, the other leg is 4
