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°**](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcd6a00b4-58c5-4c56-90a0-b3d1ffab1444%2F1874335c-6251-42c9-99bd-a52a55dd801c%2Ft4wnglo_processed.jpeg&w=3840&q=75)
