Question
If an angle has a measure of 155°, what is the measure, in degrees of an angle that is supplementary to it
**Question 11**

*If an angle has a measure of 155°, what is the measure, in degrees, of an angle that is supplementary to it?*

This question provides a visual diagram of an angle measuring 155°, indicated by a label next to the angle. The question aims to find the measure of the unknown supplementary angle.

**Answer Choices:**

1. 22.5°
2. None of the other answers are correct
3. 35°
4. 25°
5. 15°

*Explanation:*

Supplementary angles are two angles that add up to 180°. To find the measure of the unknown angle that is supplementary to 155°, perform the following calculation:

180° - 155° = 25°

Therefore, the correct answer is:

**25°**
