(C)
Step-by-step explanation:
What are supplementary angles?
- Supplementary angles are angles that add up to 180°. They're usually adjacent angles, but not all the time.
Given the information above, C) is correct because ∠AXD and ∠DXC are right angles. One right angle is worth 90°, so two adjacent right angles must be worth 180°, thus being supplementary.
