Answer:

x = 40

Step-by-step explanation:

Lines and Angles

The image shows the shape of a triangle, whose base is extended to form a linear pair of angles.

Recall that two linear angles add up to 180°, this forms the equation:

x + 4x - 20 = 180

Simplifying:

5x = 180 + 20 = 200

x = 200/5 = 40

x = 40
