J can give you some example:
absolute (1-3)=absolute(-2)=2
Answer:
(x+1)(2x-3)(3x-5)
Step-by-step explanation:
To find the sum of the interior angles of a nonagon, divide it up into triangles... There are seven triangles... Because the sum of the angles of each triangle is 180 degrees... We get
7 * 180 = 1260°
So, the sum of the interior angles of a nonagon is 1260 degrees.
