Question

what is the measures of one angle in a regular 18-gon

Answer 1

Hello and Welcome to OpenStudy! :)

the equation is probably 180(n-2)/n = degrees of one angle
when n = number of sides

Answer 2

so plug in n = 18
-> 180(18-2)/18 = ?

Answer 3

pThe formula is:
Sum of Interior Angles=180(Number of Angles-2)

So you put 18 in for n, and get 2880 for the total sum of the angles. To find the measure of each individual angle, divide that number by 18.

Each interior angle measures 160 degrees.
