Question

3. Find the measure of each interior angle of a a) nonagon b) decagon c) 24-gon


chapter of polygon​

Answer 1

Step-by-step explanation:

A nanogon has 9 sides

and the total angle sum is using the formula n-2 ×180

so, 9- 2 ×180

1260⁰

1260⁰ divided by 9 gives 140⁰

so each interior angle is 140⁰

by using this method we can find,

decagon. 10-2×180 is 1440⁰

when divide 1440 divided by 10 is 144⁰

same use for other

Answer 2

Step-by-step explanation:

Sum of interior angles in a n-sided polygon is 180°(n-2). Similarly, sum of interior angles in decagon is 180°(8) (i.e). 1440
