I dont know but thanks for your points
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.
A: for every foot you will divide by 9 feet.
B: divide 15 by 9
You need to contact the app about that, try maybe their customer service or their email?
