cos(50) = 0.6428 (rounded)
cosine(59 degrees) = 0.51504 (rounded)
The supplement of a 50-degree angle is found by subtracting the angle from 180 degrees. Therefore, the supplement is 180 - 50 = 130 degrees. Thus, a 130-degree angle is the supplement of a 50-degree angle.
The number 1.414... (square root of 2) is two times the cosine or sine of a 45 degree angle. The reason for this is that for a 45 degree angle, the two sides are cosine and sine, they are equal, and if you solve using the Pythagorean theorem with a hypotenuse of 1, the two sides are each (21/2)/2.
The shrink constant, often referred to in the context of trigonometric functions, can be calculated using the cosine of the angle. For an angle of 15 degrees, the shrink constant is equal to the cosine of 15 degrees, which is approximately 0.9659. This means that an object or dimension shrinks to about 96.59% of its original size when projected at a 15-degree angle.

at a 45 degree angle, or pi/4
45 degree
It's a 50 degree angle. It's an angle that measures 50 degrees. It's the complementary angle of a 40 degree angle.
As a decimal: 0.866 As a fraction: √(3)/2
Cos(65 deg) = 0.4226 approx.
the cotangent of a 50 degree angle is -3.678 This is in Radians. The cotangent of a 50 degree angle is .8391 (rounded) degrees.
Any polygon can have a 50-degree angle. It doesn't have to, but it can.
A 40 degree angle is the COMPLEMENT of a 50 degree angle.
Find the cosine of 38 degrees and then find its reciprocal.
