A supplementary angle will add up to 180 degrees so to find the supplementary angle of 179 degrees, you would take 180-179 to get a 1 degree angle.
The complement of an acute angle A is the angle 90° - A. The complement of 13° is 77°.
Supplement angle: 180-65.8 = 114.2 degrees Complement angle: 90-65.8 = 24.2 degrees
An angle of 86 degrees is.
Complement = 90 degrees.
