Pythagreom Theorem help:
If b = square root of 17 and c = 9, then a = ?

--------------------------------------------------------------------

a%5E2+%2B+b%5E2+=+c%5E2

a%5E2+%2B+%28sqrt%2817%29%29%5E2+=+9%5E2

a%5E2+%2B+17+=+81

a%5E2+=+81-17

a%5E2+=+64

a+=+sqrt%2864%29 ... note: a+%3E+0 (so we don't have to worry about the minus in the plus/minus)

a+=+8
