As a start, draw what the description says.\r
\n" ); document.write( "\n" ); document.write( "From left to right on the line are points A, C, B, D.\r
\n" ); document.write( "\n" ); document.write( "Let AC=x=CB.\r
\n" ); document.write( "\n" ); document.write( "From this you find AB=2x, and BD=2x, and given is AD=24.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%2Bx%2B2x=24\"
\n" ); document.write( "\"4x=24\"
\n" ); document.write( "\"x=6\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Can you finish and find length CD ?
