Let's x cm the length of the leg, using Pythagorean Theorem we write:\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2Bx%5E2=10%5E2\"=>\"2x%5E2=100\"=>\"x%5E2=50\"=>\"x=sqrt%2850%29\"=>\r
\n" ); document.write( "\n" ); document.write( "\"x=5sqrt%282%29\"=>\"x=7.1\" cm.
\n" ); document.write( "
\n" );
