The ladder,the floor & the wall form a right triangle.
The base is one leg Leg 2 The height is the other leg leg1
The ladder acts as the hypotenuse
Pythagoras theorem

(Hyp)^2= (leg1)^2+ Leg2^2
Hypotenuse = 15 ft
leg1= 14.5 ft
Leg2= ?

leg2^2=hyp^2-leg1^2
Leg2^2= 15 ^2 - 14.5 ^2
Leg2^2= 225 - 210.25
Leg2^2= 14.75
Leg2=
Leg2= 3.84 ft
