Answer:
7 pie
Step-by-step explanation:
the sum of the interior angles of a nonagon is 1260 degrees.
Now The sum of interior angles of a convex N-sided polygon equals to π(N−2) radians.
In case N=9 (nanogon)
this sum is
π(9−2)=7π (radians)
-1=7-8
-1=-1
2602.142857 (you can simplify if you want)
just act like the fraction sign is a division sign and then divide the two number.
Hope this helped!
