Answer:
An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same.
Step-by-step explanation:
Hello!
Since the angles are same side alternate angles they are equal to each other
60 - 2x = 70 - 4x
We solve this algebraically
Add 4x to both sides
60 + 2x = 70
Subtract 60 from both sides
2x = 10
divide both sides by 2
x = 5
Hope this helps!
