The value of cos 46 degrees is approximately 0.7193. Cosine is a trigonometric function that represents the ratio of the adjacent side to the hypotenuse in a right triangle. In this case, when the angle is 46 degrees, the cosine value is calculated by dividing the length of the adjacent side by the length of the hypotenuse.

Cos is the ratio between adjacent side (of the given angle thieta) to the hypotenuse of the triangle.
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
negative one half
You can use the Pythagorean identity to solve this:(sin theta) squared + (cos theta) squared = 1.
