Answer:

x = 40

Step-by-step explanation:

Here's a fun fact, all of those angles actually add up to 360 degrees!

How do we know this? Well if you were to draw a small arc between each of the lines, you would see that the arc would end up making a circle. And remember, circles have 360 degrees!

Now we can do some basic algebra. Add up all the angles and set that equal to 360.

(2x) + (x) + (3x + 20) + (2x+20) = 360.

8x + 40 = 360

8x = 320

x = 40

Hope this helped!
