Final answer:
The measure of each interior angle of a nanogon is 160°.
Step-by-step explanation:
The measure of each interior angle of a nanogon can be found using the formula:
Interior angle = (180 x (n - 2)) / n
Where n is the number of sides of the polygon.
For a nanogon, which has 9 sides, the formula becomes:
Interior angle = (180 x (9 - 2)) / 9 = 160°
Therefore, the measure of each interior angle of a nanogon is 160°.
