Question

Find the measure of each interior angle of
A. Decgon
B. Nonagon

Answer 1

Answer:

mark as brainliest plssssss

Step-by-step explanation:

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1440 degrees (from above)... And there are ten angles... So, the measure of the angle of a regular decagon is 144 degrees.

All sides are the same length (congruent) and all interior angles are the same size (congruent).

To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)... And there are nine angles...

nonagons

So, the measure of the angle of a regular nonagon is 140 degrees.
