Answer:
number of sides of a polygon is 8(because the polygon is octagon)
sum of interior angle of a octagon=1080 degree
sum of exterior of a octagon = 360 degree
Step-by-step explanation:
here in question ,
interior angle of a polygon=3*360(exterior angle of a polygon is always 360 degree)
=1080
Octagon
Sum of interior angles = 3*360 = 1080
sum of interior angles, is also, s = (n-2)180
From that,
n-2)180 = 1080
n-2 = 1080/180
n = 6 + 2
n = 8
Therefore, the figure is an 8 sided polygon or an octagon
