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 = 26 ft
leg1= 24 ft
Leg2= ?
leg2^2=hyp^2-leg1^2
Leg2^2= 26 ^2 - 24 ^2
Leg2^2= 676 - 576
Leg2^2= 100
Leg2=
Leg2= 10 ft
The ladder touches the wall at a height of 10 ft
