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 71°
The complement is
90 = x + y
Since we are given an angle of 71° we can substitute it for x, and solve for y.
90 = y + 71 y = 19
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 + 19 y = 161
So the answer is 161°
