Answer:
The number of sides the polygon have 9
Step-by-step explanation:
Given in question as :
For The circle , the central angles measure be 40 °
Let the number of sides of polygon = n
Now . as we know
External angle = 
Or , 40° =
Or,
= 40°
Or,
= 40°
So, n =
= 9
Hence The number of sides the polygon have 9 Answer
Hundred thousand is the first 9, so we will round up to make 1 million.
Answer:
x = 26, y = 9
Step-by-step explanation:
Add the bottom equations and set them equal to 180
8x -28 = 180
8x = 208 divide each by 8
x = 26
Find the bottom right, 3(26) - 11
78 - 11 = 67
The unlabeled top left box is also equal to 67 degrees.
So 2y + 5 = 23
2y = 18
y = 9
