cosine(59 degrees) = 0.51504 (rounded)
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 cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
Acute angle
cosine(59 degrees) = 0.51504 (rounded)
60 degrees = 0.5 1/2
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.
A 40 degree angle is the COMPLEMENT of a 50 degree angle.
Cos(65 deg) = 0.4226 approx.
As a decimal: 0.866 As a fraction: √(3)/2
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.
Find the cosine of 38 degrees and then find its reciprocal.
