Which two equations can be used to determine the measure of these two adjacent angles?

Question

2x+3=x−6
3x−3=180
(2x+3)−(x−6)=180
(x+6)−(2x+3)=180
(2x+3)+(x−6)=180
chose two

Answer 1

The two equations that can be used to determine the measure of these two adjacent angles are:

1) 2x+3=x−6

2) (2x+3)+(x−6)=180
