Correct Answer: D
Explanation:
In order to solve this problem, we need to break down each word.
We need to first find the complement of 45°
The complement is
90=x+y
Since we are given an angle of 45∘ we can substitute it for x, and solve for y.
90=y+45y
=45
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+45y
=135
So the answer is 135°.
