Drawing and labeling the figure exactly as described, x being the distance from bottom of ladder to the wall on the ground,
\n" ); document.write( "\"%28x%2B3%29%5E2%2Bx%5E2=15%5E2\"
\n" ); document.write( "and in this case, the question asks for x+3.
\n" ); document.write( "(A different assigning of variables is possible.)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Simplifying the equation, you find \"x%28x%2B3%29=108=9%2A12\", and x+3 corresponds to 12 feet up the wall.
\n" ); document.write( "
\n" );
