The complement is (90 - the angle) or: how much you have to add to the angle to make 90 degrees.(90 - 72.354) = 17.646 degrees.
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.
No. By definition, the compliment to an angle is an angle whose measure would combine with the first to reach 90 degrees. Also, by definition, an obtuse angle is an angle whose measure is greater than 90 degrees. There is no angle that can be added to an angle larger than 90 degrees that will cause that angle to be 90 degrees (because the measure of an angle is inherently positive.) Therefore, there is no compliment to an obtuse angle.
an angle that is 54 degrees less than 4 times its complement
