40 ......................

Answer:

B

Step-by-step explanation:

When two angles are on the interior like that, they are adding up to 180 degrees in total.

So, x would be 20 because

2x+60=

2 times 20, plus 60 = 100

and 3x+20=

And 3 times 20, plus 20 = 80

Adding up 100 and 80, you get 180 degrees.

I hope this helps. I'm a student too but I hope I explained it relatively ok.
