1) Gathering the data
Angle's supplement: 180 -x
1.1) Let a =82 and b =98 we can say a is supplementary to b and vice versa, because a+b= 82+98 = 180º.
In this case.
The supplement of an angle is the difference to 180º.
If an angle's supplement is 51º less than the measure
then we can say 180 -51=129 So, 129 is the measure of the supplement of 51 and 129 because 129+51 = 180º
2) So if the measure of the angle is 51º degrees lesser than the other the measure of the other angle (supplementary) is 129º
So, 51º and 129º
