Yes, stop signs are octagon shaped. So, true.
The picture is completely black I’m not sure if that’s what you’re trying to fix but I think you didn’t uploads it correctly.
Answer: X=18
Step by Step:
2−10+x=6−8+12
Step 1: Simplify both sides of the equation.
2−10+x=6−8+12
2+−10+x=6+−8+12
(x)+(2+−10)=(6+−8+12)(Combine Like Terms)
x+−8=10
x−8=10
Step 2: Add 8 to both sides.
x−8+8=10+8
x=18

Answer: The angle measurements stay the same when the figure is enlarged or reduced
