Answer:

90°

Step-by-step explanation:

The supplement of an angle is what, when added to it, equals 180°.

So if we have 90°, we would subtract 90° from 180° to get 90°.

The supplement of 90° is 90°.

The complement of 85° is 5°, since they add up to equal 90° a right angle. So the complement of 90° is 0°
