The measure of it's supplement is 117. You do 180 minus 63 and that makes 117.
Answer:

Step-by-step explanation:
The cotangent function can be rewritten by trigonometric relations, that is:
(1)
By taking approach the periodicity properties of the cosine and sine function (both functions have a period of 360°), we use the following equivalencies:
(2)
(3)
By (2) and (3) in (1), we have following expression:

If we know that
and
, then the result of the trigonometric expression is:


Sadly there is no way to graph properly on this website.
