Do you mean #18^o#?
If so, the complement is #72^o" and the supplement is #162^o#.

Explanation:

The complement of an angle is a second angle that adds to the first to make a right angle. So subtract any angle measure that's less than #90^o# from #90^o#.
Likewise, the supplement of an angle is the angle you add to the original to make #180^o#.
