Detailed Solution

Given, two supplementary angles differ by 44°.
When the sum of a pair of angles is 180 degrees then they are called supplementary angles.
Let one of the angles be x°.
So the other angle should be 180 - x°.
According to the question,
x-(180-x)=44.
x - 180 + x = 44
x = 112
The other angle is 180-x=180 - 112=68.
Hence the two angles are 112° and 68°.
So, option 1 is correct.
