Question

If the sum of interior angles of polygon is 1800

Answer 1

12 sides

Explanation:

Given

`Sum =1800^o`

Required

The number of sides of the polygon

The sum of interior is calculated using:

`Sum = 180 * (n - 2)`

Where

`n \to` number of sides

So, we have:

`Sum = 180 * (n - 2)`

`1800 = 180 * (n - 2)`

Divide both sides by 180

`10 = n - 2`

Add 2 to both sides

`12= n`

`n=12`
