a^2 + b^2 = c^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x^2 + 7^2 = 25^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x^2 + 49 = 625\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x^2 = 625 - 49\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x^2 = 576\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = sqrt(576)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 24\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The ladder reaches 24 ft up the wall.
