40
complement angle to 40 degrees is 90 - 40 = 50 degrees and the supplement angle to 40 degrees is 180 - 40 = 140 degrees.
85
Its a very simple one: The complement of an angle is what, when added to it, equals 90 degrees (90°). For example, in your problem, 90°-85°=5°. This means that the complement of 85° is 5°, since they add up to equal 90 degrees a right angle.
