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

y=mx+b

step-by-step explanation:

m slope

b y-intercept

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
