# Trigonometry

If you know that cos(γ) = sin (806°), what is the angle γ?

γ =  4 °

### Step-by-step explanation:

$\gamma =\frac{180}{\pi }\mathrm{arccos}\left(\mathrm{sin}\left(80{6}^{\circ }\right)\right)=4\text{°}$ Did you find an error or inaccuracy? Feel free to write us. Thank you! Tips to related online calculators
