\n" ); document.write( "Equation:
\n" ); document.write( "5x + 7x + 8x = 80
\n" ); document.write( "20x = 80
\n" ); document.write( "x = 4
\n" ); document.write( "----
\n" ); document.write( "Sides of the similar triangle:
\n" ); document.write( "5x = 20
\n" ); document.write( "7x = 28
\n" ); document.write( "8x = 32
\n" ); document.write( "==============
\n" ); document.write( "Longest side is 32
\n" ); document.write( "==============
