Question

find the number of sides of a regular polygon if its angle sum is 1260 degrees​

Answer 1

9

We know that sum of interior angles of a regular polygon is (n - 2) * 180. (1) Given sum of interior angles = 1260. n = 9. Therefore the number of sides = 9.

Answer 2

Answer:

9

Step-by-step explanation:

Using (n - 2) * 180, we can find that 1260/180 is 7, and then adding two makes it 9.
