The ladder ,ground and the wall form a right triangle
\n" ); document.write( "ground distance = leg2
\n" ); document.write( "height at which ladder touches
\n" ); document.write( "Hypotenuse = ladder length
\n" ); document.write( "Pythagoras theorem states that
\n" ); document.write( "
\n" ); document.write( "Hypotenuse ^2= leg1^2+leg2^2
\n" ); document.write( "
\n" ); document.write( "Hypotenuse = 25 ft
\n" ); document.write( "leg1 = 20 ft
\n" ); document.write( "
\n" ); document.write( "leg2^2= hypotenuse ^2 - leg1^2
\n" ); document.write( "
\n" ); document.write( "Leg2^2= 25 ^2 - 20 ^2
\n" ); document.write( "Leg2^2= 625 - 400
\n" ); document.write( "Leg2^2= 225
\n" ); document.write( "take the square root
\n" ); document.write( "leg2= 15 ft
\n" ); document.write( "
\n" ); document.write( "Distance of ladder on ground = 15 ft
