Make a right triangle with the 25 ft ladder being the hypotenuse, and 8 feet being the bottom leg.
\n" ); document.write( "We know that
\n" ); document.write( "a^2 + b^2 = c^2
\n" ); document.write( "Now we solve for b...
\n" ); document.write( "b^2 = c^2 - a^2
\n" ); document.write( "b^2 = 25^2 - 8^2
\n" ); document.write( "b^2 = 625 - 64
\n" ); document.write( "b^2 = 561
\n" ); document.write( "Taking the square root of both sides...
\n" ); document.write( "b is about 23.7 feet
\n" ); document.write( "
