A regular polygon of "n" sides has "n" Lines of Symmetry
so a regular 32 sided polygon has 32 lines of symmetry
20/(7-3) The difference of seven and three have to be in the parentheses because 20 is divided by the difference of the numbers not the numbers themselves.
Minus the 10 from the 50, which makes 40. then divide 40 by 8
50-10=40
40÷8=5
n=5

Answer: x = -12</h3>
=======================================================
Work Shown:
Let's label angle 2 as y, so y = x+132.
Also, let's add another variable z. We'll make z equal to the angle adjacent and supplementary to angle y. So y+z = 180
Solve for z to get
z = 180-y
z = 180-(x+132)
z = 180-x-132
z = 48-x
This angle z is added to the 90 degree angle to get the measure of the exterior angle 150 degrees. This is through the remote interior angle theorem.
So,
z+90 = 150
48-x+90 = 150
138-x = 150
-x = 150-138
-x = 12
x = -12
