Answer:

x = 3

Step-by-step explanation:

According to parallel lines, the angle above 40x degrees is 20x because of corresponding angles in a parallel line.

Corresponding angles in || lines are congruent to each other.

A straight line is 180 degrees

20x + 40x = 180

Combine like terms

60x = 180

Divide by 60 on both sides to isolate x

x = 3

Hope this helps :)

Have a nice day!
