Create an image of a nonagon, with seven of its angles emphasized in a unique color, perhaps blue, and the remaining two angles are depicted in a different color, probably red. The nonagon should be on a neutral background. The image should not contain any text.

The sum of seven of the angle of a nonagon is 1000 . The other two angle are equal to each other. Calculate the sizes of the other two angles

(n-2) 180

9-2×180
7×180=1260
Sum of seven angles =1000
Sum of the other two = 1260
1260-1000=260
Size of each angle =260/2=130°

A nonagon has nine sides and nine angles.

Use the formular-sum of angles of polygon=(n-2)*180°.
In a nonagon, n=9.
sum of angles= (9-2)*180°
=7*180°
=1260°
sum of seven of the angles=1000°
sum of the other two angles=1260°-1000°
=260°
size of each angle=260°/2=130°.
I hope this will help.

Thanks

God bless you oobleck, your answer really helped me with my assignment

Thanks you just helped me

well, since the sum of all 9 angles is 7*180 = 1260 you should be able to answer the question.

Thanks lilian. You just helped me now.
