Answer:
360/19 = 18.94
Step-by-step explanation:
General formula for finding the size of a regular polygon’s exterior angle is 360/n where n is the number of sides. A walk around the perimeter of the polygon would find the walker take one full turn, 360 degrees, and in a regular polygon this will be broken down in to n turns, one for each side walked down.
