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 48°.
The complement is
90=x+y
Since we are given an angle of 48∘ we can substitute it for x, and solve for y.
90=y+48y
=42
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+42y=138
So the answer is 138°
