Answer: 12.19 ft

Explanation:

Given

Length of ladder is
23 ft

Angle of elevation is
58^(\circ)

Suppose the bottom of the ladder is x ft away from the bottom of the wall

from the figure, we can write


\Rightarrow \cos 58^(\circ)=(x)/(23)\\\\\Rightarrow x=23\cos 58^(\circ)\\\Rightarrow x=12.19\ ft

Thus, the distance is 12.19 ft
