Incorrect. The ladder, the wall, and the ground form a right triangle. Let x represent the unknown distance, which is the side adjacent to the $\displaystyle{{75}}^{\circ}\usepackage{cmbright}\Huge\$ angle. You are given the length of the hypotenuse, so you can use cosine to set up an equation. Solve the equation for x, then use a calculator to find a numerical value. Round off to the nearest tenth.
