which 2 sides ?
Pythagorean Theorem = a^2 + b^2 = c^2
which side do you need?
The hypotenuse is the longest side.
for example 7^2 + 11^2 = c^2
then
49 + 121 = 170
Therefore, the answer is the square root of 170.
But you may have
7^2 + b^2 = 11^2 which would be 49 + b^2 = 121
so b would be the square root of 72
Can you show me the exact problem??
