0.5735764264 (nearest 10 decimal places).
The cosine of 20 degrees is 0.93969262
cos(55) = 0.022126756261956
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.
You cannot. The cosine of 30 degrees is an irrational number.

The cosine of 70 degrees is 0.34202014332567.
The cosine of 20 degrees is 0.93969262
It is 0.9849
cos(35)sin(55)+sin(35)cos(55) If we rewrite this switching the first and second terms we get: sin(35)cos(55)+cos(35)sin(55) which is a more common form of the sin sum and difference formulas. Thus this is equal to sin(90) and sin(90)=1
In degrees they are the same value.
