Solution

Explanation
Supplementary angles- When the total of two angles is 180 degrees, supplementary angles are formed.
To put it another way, supplementary angles are created by adding two angles together while maintaining a straight angle.
Hence, If the sum of measures of two angles is $180 °$ , then they are Supplementary.
