We know that the sum of all the exterior angles will add up to 360°.
We can solve this using an expression:
360/n
n = the number of sides (in the problem, we are given 19 sides)
Solve with the given value:
360/19
18.947368
Round to the nearest tenth:
18.947368 → 18.9
Therefore, the answer is 18.9
Best of Luck!
