The sum of the interior angles
2 answers:
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
