Answer 3

1. What is the sum of the interior angle measures of a 20-gon? (1 point)
a. 360
b. 3240
c. 3600
d. 162* my answer

Answer 4

45 is the answer

Answer 5

for which one

Answer 6

The exterior angles of a polygon always add up to 360 degrees.

If you have a regular octagon, it will have 8 sides (and obviously 8 exterior angles).

360 / 8 = 45° degrees.

Answer 7

Each exterior angle of a regular12-sided polygon measures 360/12=30 degrees
Therefore each interior angle measures
180-30=150 degrees

Answer 8

sum of an interior angle of a regular polygon = 180º(n – 2)
for 20-gon = 180 * (20 -2) = 3240º

Answer 9

done?

Answer 10

What is the value of x in the regular polygon below?
A Regular Polygon is a polygon with all sides and all angles equal.
so 360/6=30degrees each angle. so x=10 degrees.
