Question

The sum of the interior angle measures of a convex polygon is 1620° . how many sides does it have?the sum of the interior angle measures of a convex polygon is 1620° . how many sides does it have?

Answer 1

no. of sides
=1620/180+2
=11

Answer 2

If you are given a convex polygon with
`n` sides and
`S` is the sum of the measures of the interior angles then
`S = 180(n - 2)`.

So,
`1,620 = 180(n-2)`.

`n-2=9`

`n=11`

The polygon has 11 sides.
