To determine which two angle measures correspond to a supplementary pair, we need to find two angles that add up to 180°.
The given angles are:
- 89°
- 135°
- 112°
- 68°
Now, let's check the pairs:
- 89° + 135° = 224° (not supplementary)
- 89° + 112° = 201° (not supplementary)
- 89° + 68° = 157° (not supplementary)
- 135° + 112° = 247° (not supplementary)
- 135° + 68° = 203° (not supplementary)
- 112° + 68° = 180° (supplementary)
The angles 112° and 68° add up to 180°.
Thus, the supplementary pair is:
- Smaller angle: 68°
- Larger angle: 112°
So the final answer is:
- Smaller angle: 68°
- Larger angle: 112°
