Question

How many sides does the regular polygon have if each interior angle measure is four times the (1 point)

measure of each exterior angle measure?

Answer 1

The exterior and interior angles must add up to 180 degrees. Thus, 180 divided by five gives the exterior angle as 36 degrees (and hence the interior angles as 144 degrees).

Answer 2

10 Sides

Explanation:

Int Angle + Ext Angle = 180

4Ext + Ext = 180

Ext = 36 degrees

-----

360/36 = 10 sides
