What is the sum of the measures of adjacent angles?

Back

The sum of the measures of adjacent angles can vary, but they can be complementary (sum to 90°) or supplementary (sum to 180°).

If one angle measures 123°, what is the measure of its adjacent angle if they are supplementary?

Back

The adjacent angle would measure 57° (180° - 123° = 57°).
