90 degrees
It is not. The angle of reference is 2*pi radians or 360 degrees.
The cotangent function is the reciprocal of the tangent function, so cot(115 degrees) is equivalent to 1/tan(115 degrees). Since tan(115 degrees) is equivalent to -tan(65 degrees) due to the periodicity of the tangent function, cot(115 degrees) simplifies to -tan(65 degrees), which corresponds to option A.

Cosecant(115 deg) = 1/sine(115 deg) = 1/0.9063 = 1.1034
115 degrees is an obtuse angle
The reference angle for an angle with the measure of 175 degrees is 5 degrees
Not too sure of your question but if one angle measures 115 degrees then the other 3 angles are 115 degrees, 65 degrees and 65 degrees because opposite angles are equal.
an obtuse angle
Quadrantals are their own reference angle, so 90 degrees.
It is: 180-115 = 65 degrees
90 degrees
353 degrees is a reflex angle
It is an obtuse angle
It is not. The angle of reference is 2*pi radians or 360 degrees.
Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.
complementary angle.
