Answer:

250°

Step-by-step explanation:

360° - the know angles

360 - 20 - 70 - 20 = 250°

Step-by-step explanation:

Well this is a full circle, and in a full circle, theres 360 degrees.

So if we add up 20, 70 and 20 degrees, it comes to a total of 110 degrees.

If we subtract 110 d from 360 d, we get 250 degrees. Therefore,

X = 250 degrees
