The measure of the supplement of the angle 179° is

The correct answer is: 1°

If the sum of the measures of two angles is 180 degrees , the angles are called supplementary angles.

Here, supplement of the angle 179° and 179° are added to get 180 degrees.

supplementary angle = 180° − given angle

supplement of 179° = 180° – 179° = 1°.

Therefore, the measure of the supplement of the angle 120° is 60° .
