Incorrect. The ladder, the wall, and the ground form a right triangle. Let x represent the unknown height, which is the side opposite the $\displaystyle{{70}}^{\circ}\usepackage{cmbright}\Huge\$ angle. You are given the length of the side adjacent to this angle, so you can use tangent 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.
