\n" ); document.write( "one side = 4
\n" ); document.write( "let other side be x
\n" ); document.write( "..
\n" ); document.write( "they form a right triangle.
\n" ); document.write( "so use pythagoras theorem
\n" ); document.write( "diagonal is hypotenuse
\n" ); document.write( "..
\n" ); document.write( "x^2+4^2= 5^2
\n" ); document.write( "x^2+16=25
\n" ); document.write( "x^2= 25-16
\n" ); document.write( "x^2= 9
\n" ); document.write( "x= 3 the other sides
