Question

The sum of all interior angles in a polygon is 9 degrees. How many sides does the polygon have? Please show your working.

Answer 1

i think it’s 2.05

this is because to find the interior angles in a polygon, we use the equation:

(number of sides - 2) x 180

therefore to find the amount of sides, we reverse it:

(sum of interior angles / 180) + 2
(9/180) + 2
0.05 + 2
2.05
