We need to use Pythagorean theorem here as
\n" ); document.write( " $\"a%5E2+%2B+b%5E2+=+c%5E2\"$
\n" ); document.write( "let a = 3 and c = 4, we get
\n" ); document.write( " $\"3%5E2+%2B+b%5E2+=+4%5E2\"$
\n" ); document.write( "which is
\n" ); document.write( " $\"9+%2B+b%5E2+=+16\"$
\n" ); document.write( " $\"b%5E2+=+7\"$
\n" ); document.write( " $\"b+=+sqrt%287%29\"$ \n" ); document.write( "

\n" );
