#### Two angles are supplementary and one exceeds the other by 10 degree. Find the angles.

Let the measure of one angle be x then other angle is x+10.

As the angles are supplementary

X+ (x+10)=180

2x + 10= 180

2x = 170

X = 170/2

X = 85

Hence, the angles are 85 and 95.

As the angles are supplementary

X+ (x+10)=180

2x + 10= 180

2x = 170

X = 170/2

X = 85

Hence, the angles are 85 and 95.
