Final answer:
The complement of 40 degrees is 50 degrees and the supplement of 40 degrees is 140 degrees.
Step-by-step explanation:
The complement of an angle is the difference between 90 degrees and the angle. In this case, the complement of 40 degrees is 90 - 40 = 50 degrees.
The supplement of an angle is the difference between 180 degrees and the angle. In this case, the supplement of 40 degrees is 180 - 40 = 140 degrees.
So, the complement of 40 degrees is 50 degrees and the supplement of 40 degrees is 140 degrees.
