Incorrect. Let x equal the length of the line, which is the hypotenuse of a right triangle formed with the right side of the wall and the base of the wall. The base of the wall is the side adjacent to the $\displaystyle{{25}}^{\circ}\usepackage{cmbright}\Huge\$ angle, and its length is 16 feet. Therefore, you can use the cosine function to set up an equation:

$\displaystyle{{\cos{{25}}}}^{\circ}=\frac{{16}}{{x}}\usepackage{cmbright}\Huge\$

Solve this equation for x, use your calculator to find a numerical value, and round off to the nearest tenth.
