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.
Answer:
Step-by-step explanation:
Let the number be x
4times a number =4x
The difference of four times a number and seven : 4x - 7
4x - 7 = 13
4x = 13 + 7
4x = 20
x = 20/4
x = 5
