The ladder,the floor & the wall form a right triangle.
\n" ); document.write( "The base is one leg The height is the other leg
\n" ); document.write( "The ladder acts as the hypotenuse
\n" ); document.write( "Pythagoras theorem
\n" ); document.write( "
\n" ); document.write( "(Hyp)^2= (leg1)^2+ Leg2^2
\n" ); document.write( "Hypotenuse = 15 ft
\n" ); document.write( "leg1= 12 ft
\n" ); document.write( "Leg2= ?
\n" ); document.write( "
\n" ); document.write( "leg2^2=hyp^2-leg1^2
\n" ); document.write( "Leg2^2= 15 ^2 - 12 ^2
\n" ); document.write( "Leg2^2= 225 - 144
\n" ); document.write( "Leg2^2= 81
\n" ); document.write( "Leg2= $\"sqrt%28%0981%09%29\"$
\n" ); document.write( "Leg2= 9 ft
\n" ); document.write( "
\n" ); document.write( "The ladder touches the wall at a height of 9 ft
