\n" ); document.write( "\n" ); document.write( "A triangle has sides of \"3\", \"9\", and \"11\". \r
\n" ); document.write( "\n" ); document.write( "In a similar triangle, sides will be proportional to sides given above.\r
\n" ); document.write( "\n" ); document.write( "if in a similar triangle the shortest side is \"6\", it is proportional to the shortest side above which is \"3\"\r
\n" ); document.write( "\n" ); document.write( "so, \"6%3A3\" \r
\n" ); document.write( "\n" ); document.write( "and, if the longest side is \"x\", it is proportional to the longest side above which is \"11\"\r
\n" ); document.write( "\n" ); document.write( "so, \"x%3A11\" \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "then, a proportion that models the situation is: \"6%3A3=x%3A11\" \r
\n" ); document.write( "\n" ); document.write( "\"6%3A3=x%3A11\" ....solve the proportion for \"x\"\r
\n" ); document.write( "\n" ); document.write( "\"6%3A3=x%3A11\"...cross multiply\r
\n" ); document.write( "\n" ); document.write( "\"6%2A11=x%2A3\"\r
\n" ); document.write( "\n" ); document.write( "\"66=3x\"\r
\n" ); document.write( "\n" ); document.write( "\"66%2F3=x\"\r
\n" ); document.write( "\n" ); document.write( "\"22=x\"\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
