the total angle inside the U-shaped is 180 degree.

110 + (8x-10) = 180

8x-10 = 70
8x = 80

x = 10
grain
The answer is 10
8(10)-10=70
If you take the measurements of the two angles that are given their sum should equal 180
So you subtract 110 from 180 to find out what 8x-10 should equal.
180-110=70
Therefore
8x-10=70
Add 10 to both sides
8x=80
Divide by 8 on both sides
x=10
