If two angles are supplementary, then the sum of their measure is ____

Open in App

Solution

Solve for sum of two supplementary angles.
If two angles are supplementary, then the sum of their measure is $180 °$
Let us consider two angles $112 °, 68 °$
In order to determine whether the angles are supplementary or complementary , we have to find the sum of the given angles.
Sum is $112 ° + 68 ° = 180 °$
Therefore $112 °, 68 °$ are supplementary angles because the sum of their measure is $180 °$ .
Hence if two angles are supplementary, then the sum of their measure is $180 °$
