The supplementary angle of an angle is the angle that, when added to the original angle, equals 180°.
To find the supplementary angle of an angle, subtract the measure of the original angle from 180°.
180° - 161.2° = <<180-161.2=18.8>>18.8°
Therefore, the measure of the supplementary angle is 18.8°.
