Work out the number of sides of a regular polygon with interior
angle 172

number of sides =

45 sides

Step-by-step explanation:

Using the property:

Interior angle + exterior angle = 180°

exterior angle = 8°

now, using the formula:

number of sides = 360/exterior angle

number of sides = 360/8

number of sides = 45 ANS.
