Step-by-step explanation:

x + (4x - 20) = 180

5x - 20 = 180

5x = 180 + 20

5x = 200

x = 200/5

x = 40°

Answer:

[tex]x = 40[/tex]

Answer D is correct

Step-by-step explanation:

Angles in a straight line is added up to 180°

Therefore,

[tex]x + 4x - 20 = 180 \\ 5x - 20 = 180 \\ 5x = 180 + 20 \\ 5x = 200 \\ \frac{5x}{5} = \frac{200}{5} \\ x = 40 \degree[/tex]

Hope this helps you.
