Hi there,
\n" ); document.write( "Make the two legs = x
\n" ); document.write( "By Pythagoras Theorem
\n" ); document.write( "x^2 + x^2 = 20^2
\n" ); document.write( "2x^2 = 400
\n" ); document.write( "x^2 = 400/2
\n" ); document.write( "x^2 = 200
\n" ); document.write( "x = √200
\n" ); document.write( "x = 14.14 inches (2 decimal places)
\n" ); document.write( "Hope this helps :-)
