Answer:
x =20
Step-by-step explanation:
As a line is 180 degrees
So 7x + 40 would be 180, which would lead us with the equation:

=x =20 (divide both sides by 7)
The answer is -2. The line is going from left to right which makes it negative. Then if you look at the line and do change in y(rise) over change in x(run).
