let second side be x
\n" ); document.write( "first side =2x\r
\n" ); document.write( "\n" ); document.write( "third side = x+5\r
\n" ); document.write( "\n" ); document.write( "Add them up\r
\n" ); document.write( "\n" ); document.write( "x+x+5 +2x =26\r
\n" ); document.write( "\n" ); document.write( "4x+5=26\r
\n" ); document.write( "\n" ); document.write( "4x = 21
\n" ); document.write( "x= 21/4\r
\n" ); document.write( "\n" ); document.write( "x= 5.25
\n" ); document.write( "2x = 10.5
\n" ); document.write( "x+5 = 10.25\r
\n" ); document.write( "\n" ); document.write( "scalene triangle
