Answer:
12
Step-by-step explanation:
The sum of the exterior and interior angles = 180°
let x be the measure of the exterior angle then interior angle is 5x and
5x + x = 180
6x = 180 ( divide both sides by 6 )
x = 30
The sum of the exterior angles of a polygon = 360°, thus
number of sides = [tex]\frac{360}{30}[/tex] = 12
