Answer:
The reference angle for an angle whose measure is -440 is 80.
Step-by-step explanation:
Reference angle--
It is the angle which is made from the terminal side of the given angle and it is always made by taking x-axis as a reference.
Here we are given a angle whose measure is:
-440.
This means that the angle covers more than one rotation and ends in the fourth quadrant.
Hence, the reference angle is:
-440+360=80
