Answer :
The polygon is a hexagon and the value of x in the figure is 100
How to determine the value of x?
The polygon is a hexagon, because it has 6 sides
So, the sum of angles in it is:
Sum = 180(6 - 2)
Evaluate
Sum = 720
The sum of angles in the shape are:
x + 90 + x+ 9 + 145 + 156 + 120 = 720
Evaluate thelike terms
2x = 200
Divide both sides by 2
x = 100
Hence, the value of x in the figure is 100
