Well, isn't that a happy little math problem we have here? When we take 90 away from 180, we're left with 90. Just like painting a beautiful sky, sometimes we need to subtract a little to see the true beauty of what's left behind.

Well, honey, 180 minus 90 is 90. It's not rocket science, but I'm glad you came to me for that earth-shattering calculation. Keep those math questions coming, I'm just getting warmed up.
Complementary angles are found by subtracting a random angle from 90 degrees for complementary always and 180 for supplementary always
It is 205 minus 25 = 180
An acute angle is an angle that is between 0 and 90 degrees. The supplement of the angle is 180 degrees minus the magnitude of the angle. Since the original angle is greater than 0 degrees, the supplement must be less than 180-0 = 180 degrees. Since the original angle is less than 90 degrees, the supplement must be greater than 180-90 = 90 degrees. Thuis, the supplement measures between 90 and 180 degrees - that is, it is an obtuse angle.
180 - 158 = 22
180 - 92 = 88
