What is the value of x in this diagram

To figure this out, use this equation because the angles are corresponding and marked congruent:
2x + 10 = 4x - 20
Subtract 10 from each side:
2x = 4x - 30
Now subtract 4x from each side:
-2x = -30
Divide by -2:
x = 15

The measures of the angles are 40

Hope this helps!

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
