Question

I need the answer to x. The picture didnt load last time-

Answer 1

X=20

Explanation:

When you add 7x and the x+20, they total to 180 degrees to form a flat angle so to solves this use equation 7x+x+20=180 to get x=20.

To check: input the 20 into both equations and see if they add up to 180 degrees

7x20=140

20+20= 40

140+40= 180

Answer 2

x = 20º

Explanation:

7x + x + 20 = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = 160 / 8

x = 20

Hope that helps!
