Find the measure of one interior angle of a regular 7-gon

128.57 degrees

Step-by-step explanation:

To find the measure of an interior angle of a regular polygon with sides, we can use the formula:

To find the measure of an interior angle of a polygon with 7 sides, all we have to do is plug in 7 into the formula:

7 minus 2 equals 5, so the answer is

÷

180 times 5 is equal to 900, and 900 divided by 7 is approximately 128.57

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
