The cosine of 450 degrees can be found by first reducing it to an equivalent angle within the standard range of 0 to 360 degrees. Since 450 degrees is equal to 450 - 360 = 90 degrees, we find that cos(450 degrees) = cos(90 degrees). Therefore, cos(450 degrees) is equal to 0.
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
Cos(120) = -0.5
Cosine (23) = Cos(23 degrees) = 0.920504853... ~ 0.9205
Cos of 850 degrees?850 deg = 130 + 360*2 = 130 degBy the graph of the cosine: cos(130) = -cos(50)and cos(50) is not a fraction of a root.cos(50) = 0.6427876...Therefore, cos(850) = -0.6427876...

Well, darling, 150 degrees Celsius is equivalent to 302 degrees Fahrenheit. So, if you're baking or cooking something at 150 degrees Celsius, just remember to convert it to Fahrenheit if you want to avoid a kitchen disaster.
150 degrees Celsius is 302 degrees Fahrenheit. 150 degrees Fahrenheit is 65.6 degrees Celsius.
cos(495) = cos(495-360) = cos(135) = -cos(180-135) = -cos(45) = -sqrt(1/2) or -1/sqrt(2)
150 degrees Celsius is equivalent to 302 degrees Fahrenheit.
150 degrees Fahrenheit = 65.5 degrees Celsius.
-150 degrees below 0 Celsius is equivalent to -238 degrees Fahrenheit.

The statement of the problem is equivalent to sin x = - cos x. This is true for x = 135 degrees and x = -45 degrees, and also for (135 + 180n) degrees, where n is any integer.
The value of cos 40 degrees is approximately 0.766.
