Supplementary angles' sum = 180 degree
Let angle be x.
So, another angle would be 180 - x
Given that 180 - x - x = 23
180 - 2x = 23
2x = 180 - 23 = 157
x = 157/2 = 78.5 degree

Let the smaller angle be x degree
Then bigger angle be x+23
Sum of suplementary angles =180 degrees.
Then x + (x +23)= 180
2x +23=180
2x= 180-23
2x=157
x= 157/2
x=78.5 degrees
Therefore smaller angle =78.5 degrees
Bigger angle = 101.5 degrees.
