Question

each interior angle of a palygon is 108°find the number of sides of the polygon​

Answer 1

Answer:

If interior angle = 108°

Then exterior angle = 360° - 108° = 72°

=》 Number of sides = 360°/72°

=》 5 sides

Answer 2

Answer:

(n-2) ×180=108×n

Step-by-step explanation:

(n-2)×180=108n

180n-360=108n

180n-108n=360

n=360÷72

THEREFORE n=5 .
