Webb17 okt. 2024 · Since a regular polygon has congruent sides (every side is equal to each other) you set up the equation 5-2x = -4x+9 then you solve for "x". After solving for "x", you substitute the answer you got from "x" back into the one of the expressions from one of the sides. You should get the answer of how many units one of the sides is. WebbUse the above formula to find the perimeter of the nonagon. p = 9 * 8. Substitute in the known value. p = 72. Multiply the side length, eight, by the total number of sides, nine for …
