Answer:
1. 3a2
Step-by-step explanation:
Answer:
Let the two supplementary angles be
we know sum of two supplementary angles is 180
2x + 3x = 180
5x = 180
x = 180/5
x = 36
2*36 = 72
3*36 = 108
Therefore the two supplementary angles are 72 and 108
Answer:
I haven't done expressions in a while but I say the safest bet would be D.
All of them are true except AD = GH.
