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

C. mAngle1 + mAngle2 = 180.

Explanation: This is the correct answer on Edge 2021, just took the Unit test and made a 100%. Hope this helps ^-^.

Answer 2

C.

m<Angle1+m<angle2 will add to 180 since the sum of supplementary angles are equal to 180°.
