Question

In a regular polygon one of its inner angle is three times outer angle .what is the name of the regular polygon?

Answer 1

Answer:

The sum of exterior angles of any figure is 360. It does not matter how many sides it contains. It is always 360.

The sum of the interior angles of any figure is 180(n-2) where n = number of sides.

The equation would be 180(n-2) = 3*360.

Instead of multiplying the right side out, just divide both sides by 180. You get (n-2) = 3*2 so n-2=6 and n=8.
