You probably set up the equation incorrectly, setting $\displaystyle{{\sin{{65}}}}^{\circ}\usepackage{cmbright}\Huge\$ equal to $\displaystyle\frac{{x}}{{14}}\usepackage{cmbright}\Huge\$ . A correct way to set up the equation is $\displaystyle{{\tan{{65}}}}^{\circ}=\frac{{14}}{{x}}\usepackage{cmbright}\Huge\$ . Solve this equation for x and round off.
