Well you see it is a really simple one to do x should be 9 trust me its 9 even tho it dont sound correct

Answer:

x = 14

Step-by-step explanation:

"Regular" means all the angles are the same. So all of the angles will be 9x-18. Next, the total of all the angles added up is 540°

5 (9x - 18) = 540

Divide both sides by 5

9x - 18 = 108 add 18 to both sides

9x = 126 divide by 9

x = 14
