Correct Answer: A
Explanation:
In order to solve this problem, we need to break down each word.
We need to first find the complement of 18°
The complement is
90=x+y
Since we are given an angle of 18° 18° we can substitute it for x, and solve for y.
90=y+18y
=72
Now since we need to find the supplement of the answer, we just got.
The supplement is
180=x+y
Now we simply substitute the answer we just got for x.
180=y+72y
=108
So the answer is 108°.
