The ladder,the floor & the wall form a right triangle.
The base is one leg The height is the other leg
The ladder acts as the hypotenuse
Pythagoras theorem
(Hyp)^2= (leg1)^2+ Leg2^2
Hypotenuse = 15 ft
leg1= 12 ft
Leg2= ?
leg2^2=hyp^2-leg1^2
Leg2^2= 15 ^2 - 12 ^2
Leg2^2= 225 - 144
Leg2^2= 81
Leg2=
Leg2= 9 ft
The ladder touches the wall at a height of 9 ft
