Question

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

Answer 1

angle 1 + angle 2 = 180
this is the eq which you had asked

Answer 2

Answer:

Step-by-step explanation:

Supplementary angles are angles that add up to 180°.

Lets say we have angle x and y and say they are supplementary.

Then :

x + y = 180°

Or :

x = 180° - y

y = 180° - x

The equation connecting the two is :

Angle 1 + Angle 2 = 180°
