Question 135639
The terms complementary and supplementary refer to the relationship between pairs of angles.  Two angles are complementary if and only if the sum of their degree measures is 90 (or the sum of their radian measures is {{{pi/2}}}).  To angles are supplementary if and only if the sum of their degree measures is 180 (or the sum of their radian measures is {{{pi}}}).


Since you only provided the measure of a single angle, no one can answer your question except to say that if you are comparing this angle to another that measures 90 - 53 = 37 (degrees, I have to presume, though you didn't say), then the angles are complementary.  If the other angle measures 180 - 53 = 127 then the angles are supplementary.  Otherwise, they are neither.


Given the information provided, I don't know how to be any more straightforward or correct than that.
