I'm assuming you want to find the missing leg of the right triangle (which is x). If so, then x%3E0 and solving for x gives you


%28sqrt%285%29%29%5E2+%2B+x%5E2+=+7%5E2


5+%2B+x%5E2+=+49


x%5E2+=+49-5


x%5E2+=+44


x+=+sqrt%2844%29 Ignore the negative square root since x%3E0


x+=+sqrt%284%2A11%29


x+=+sqrt%284%29%2Asqrt%2811%29


x+=+2%2Asqrt%2811%29 Exact length


x+=+6.6332495807108 Approximate length (using a calculator to compute)

Sqrt(5)^2 + x^2 = 7^2
--------------
5 + x^2 = 49
x^2 = 44
x+=+sqrt%2844%29
x+=+-sqrt%2844%29
