$\frac{\cos 77}{\sin 77}$ $\approx$ 0.23086819

Work Step by Step

$\frac{\cos 77}{\sin 77}$ $\frac{\cos\theta}{\sin\theta}$ = $\cot$ $\theta$ Therefore: $\frac{\cos 77}{\sin 77}$ = $\cot$ 77$^{\circ}$ $\cot$ 77$^{\circ}$ $\approx$ 0.23086819 Therefore: $\frac{\cos 77}{\sin 77}$ $\approx$ 0.23086819
