# Trigonometry

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

Correct result:

γ =  4 °

#### Solution:

$\gamma =\frac{180}{\pi }\mathrm{arccos}\left(\mathrm{sin}\left(80{6}^{\circ }\right)\right)={4}^{\circ }$ We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you! Tips to related online calculators
