Answer:

19 sides

Step-by-step explanation:

Sum of angles of n-side polygon = 180 *(n - 2)

180 *(n -2) = 3060

Divide both sides by 180

n- 2 = 3060/180

n - 2 = 17

n = 17+2

n = 19

Answer:

19 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here sum = 3060° , then

180° (n - 2) = 3060° ( divide both sides by 180° )

n - 2 = 17 ( add 2 to both sides )

n = 19

The polygon has 19 sides
