Answer:
B
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.
