The ladder against the wall makes a right triangle.
\n" ); document.write( "The hypotenuse, H, is the ladder length, 25 feet.
\n" ); document.write( "One side of the triangle, \"L%5B1%5D\" is 7 feet.
\n" ); document.write( "What is the other length, \"L%5B2%5D\"?
\n" ); document.write( "From Pythagorean theorem,
\n" ); document.write( "\"L%5B1%5D%5E2%2BL%5B2%5D%5E2=H%5E2\"
\n" ); document.write( "\"7%5E2%2BL%5B2%5D%5E2=25%5E2\"
\n" ); document.write( "\"49%2BL%5B2%5D%5E2=625\"
\n" ); document.write( "\"L%5B2%5D%5E2=576\"
\n" ); document.write( "\"L%5B2%5D=14\"\r
\n" ); document.write( "\n" ); document.write( "The ladder will be 14 feet away from the wall.
\n" ); document.write( "You probably want to move it a little closer before you take that first step.
