Question

ii) Find the number of sides of a regular polygon if each of the interior angel is 1680

.​

Answer 1

The formula (n-2)×180 can be used to find the sum of the interior angles of ANY polygon where n is the number of sides in the polygon.

Divide that number by n to get the measure of each individual angle of that polygon.

So substitute known values for your question.

((n-2)×180)/n = 168

So then we get 168n = 180n — 360

We then get -12n = -360

Solving for n, we get n = 30
