Answer:

$4.50\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC

$cos(A)=\frac{AC}{AB}$ -----> the cosine is the adjacent side to angle A divided by the hypotenuse

substitute the values and solve for x

$cos(68\°)=\frac{x}{12}$

$x=12*cos(68\°)=4.50\ ft$
