Question

Angles 1 and 2 are supplementary. Which equation represents the relationship between their measurements?

a. m<1 + m<2 = 90°

b. m<1 - m<2 = 90°

c. m<1 + m<2 = 180°

d. m<1 - m<2 = 180°

Answer 1

Supplementary angles sum up to 180 degrees. The equation that represents supplementary angles 1 and 2 is m<1 + m<2 = 180°, aligning with option c.

Step-by-step explanation:

The question asks which equation represents the relationship between the measurements of angles 1 and 2 which are supplementary. Supplementary angles are two angles whose measurements add up to 180 degrees. Therefore, the correct equation that represents the relationship between their measurements is m<1 + m<2 = 180°, which corresponds to option c.
