Question

Angles 1 and 2 are supplementary.

2 lines intersect to form angles 1 and 2.
Which equation represents the relationship between their measures?

mAngle1 + mAngle2 = 90°
mAngle1 + mAngle2 = 100°
mAngle1 + mAngle2 = 180°
mAngle1 + mAngle2 = 200°

Answer 1

mAngle1 + mAngle2 = 180°

Explanation:

edge 2022

Answer 2

mAngle1 + mAngle2 = 180°

Explanation:

Knowing that:

Supplementary angles are 180 degree

Solve:

The only one with 180 is the third one.

Thus, the answer is mAngle1 + mAngle2 = 180°
