Answer
$23.32\text{ ft}$
Work Step by Step
Let $x$ be the distance from $A$ to $C$.
We know that the tangent of an angle is the opposite side divided by the adjacent side.
Hence, here we can denote that
$\tan{(25^\circ)}=\dfrac{x}{50}$
Solve for $x$ to obtain:
$x=50\tan{(25^\circ)}
\\x\approx23.32\text{ ft}$
