the sum of interior angles in a polygon is 4140 how many sides does the polygon have?

Question

It has got to do with shapes

Answer 1

Formula for sum of interior angles of polygon = 180(n-2)

When n = number of sides

4140 = 180(n-2)

4140/180 = n-2

23 = n-2

Add 2 to each side.

23+2 = n-2+2

n = 25

The polygon have 25 sides.
