Question

Answer 1

Answer:

ind the measures of an interior angle and an exterior angle of a regular 18 gon.

Step-by-step explanation:

We know that the measure of exterior angle is

$( \frac{360}{n})°$

where n is the number of sides.

Here, it is given that the number of sides n=18, therefore,

$( \frac{360}{n})° = ( \frac{360}{18})° = 20°$

Hence, the measure of exterior angle is 20° .
