Answer: 12.3 ft.

Step-by-step explanation:

In the given picture we can see there is a right triangle with hypotenuse 15 ft.

Using trigonometry in the given right triangle, we have

$\cos35^{\circ}=\frac{\text{Side adjacent to}\ 35^{\circ}}{\text{Hypotenuse}}\\\\\Rightarrow\ 0.81915204428=\frac{A}{15}\\\\\Rightarrow\ A=0.81915204428\times15\\\\\Rightarrow\ A=12.2872806642\approx12.3\ ft.$
