Total number of sides = n
Half, means n/2 of them have 150° each.
Half, means n/2 of them have 170° each.
Sum of angles in a polygon is given by the formula: (n -2)*180.
So summing the first of 150 degrees and the other half of 170 would be equal to the total of (n -2)*180.
(n/2)*150 + (n/2)*170 = (n -2)*180
(n/2)*(150 + 170) = (n -2)*180
(n/2)*(320) = (n -2)*180
160n = 180n - 360
160n - 180n = -360
-20n = -360
n = (-360) / (-20). Divide out
n = 18
So the polygon has 18 sides.
I hope this helps.

Answer:
1= 0
2= 0.5
3= 1.5
4= 3
5= 5
6= 7.5
7= 10.5
8= 14
explanation: This is the edmentum answer
You just combine like terms
So 4d + - d = 3d
And 3x + 2x = 5x
So the answer is 3d + 5x
