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.
