This is a Pythagorean theorem problem, because a right triangle is formed.
\n" ); document.write( ".
\n" ); document.write( "The wall is presumed to be perpendicular to the floor. When you lean a ladder against
\n" ); document.write( "the wall, the ladder is opposite the right angle formed by the wall and the floor. Therefore,
\n" ); document.write( "the ladder is the hypotenuse of the triangle.
\n" ); document.write( ".
\n" ); document.write( "The distance measured from the intersection of the floor and the wall and up the wall to
\n" ); document.write( "the point where the ladder touches the wall (given as 17 ft) is one leg of the right
\n" ); document.write( "triangle.
\n" ); document.write( ".
\n" ); document.write( "And the distance measured from the intersection of the floor and the wall and along the
\n" ); document.write( "floor to the point where the ladder rests on the floor (given as 14 ft) is the other leg
\n" ); document.write( "of the right triangle.
\n" ); document.write( ".
\n" ); document.write( "The Pythagorean theorem says that if you square the two legs and add these squares,
\n" ); document.write( "the result is equal to the square of the hypotenuse. (Don't forget, the hypotenuse
\n" ); document.write( "is the length of the ladder. Call it L.)
\n" ); document.write( ".
\n" ); document.write( "In equation form this becomes:
\n" ); document.write( ".
\n" ); document.write( "\"17%5E2+%2B+14%5E2+=+L%5E2\"
\n" ); document.write( ".
\n" ); document.write( "Doing the squares of the numbers makes the equation:
\n" ); document.write( ".
\n" ); document.write( "\"289+%2B+196+=+L%5E2\"
\n" ); document.write( ".
\n" ); document.write( "adding the numbers on the left side:
\n" ); document.write( ".
\n" ); document.write( "\"485+=+L%5E2\"
\n" ); document.write( ".
\n" ); document.write( "Solve for L by taking the square root of both sides to get:
\n" ); document.write( ".
\n" ); document.write( "\"L+=+sqrt%28485%29+=+22.02271555\"
\n" ); document.write( ".
\n" ); document.write( "Rounding to the nearest thousandth results in the length of the ladder being 22.023 feet.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to work your way through the problem. I presume you are allowed to
