You can put this solution on YOUR website!
Your calculation is correct.
\n" ); document.write( "Check the setup of the problem.
\n" ); document.write( "If angle A is 90, and it's opposite to side a, then it's the hypotenuse (the longest side).
\n" ); document.write( "\"a%5E2=b%5E2%2Bc%5E2\"
\n" ); document.write( "\"312%5E2=216%5E2%2Bc%5E2\"
\n" ); document.write( "\"c%5E2=50688\"
