This can be calculated by using the formula: 180n–360 n 180 n – 360 n, where n = the number of sides of the polygon. In a dodecagon, n = 12. Now substituting this value in the formula. 180(12)–360 12 = 150∘ 180 ( 12) – 360 12 = 150 ∘. The sum of the interior angles of a ...
WebMar 26, 2016 · You know what the formula for the number of diagonals in a polygon is, and you know that the polygon has 90 diagonals, so plug 90 in for the answer and solve for n: Thus, n equals 15 or –12. But because a polygon can’t have a negative number of sides, n must be 15. So you have a 15-sided polygon (a pentadecagon, in case you’re curious).
