The sum of the interior angles of a polygon is (n-2)*180, n being the number of sides.
a nonagon has nine sides, so the total of interior angles is (9-2)*180=7*180
this is a regular nonagon, so each interior angle has the same degrees:
7*180/9=7*20=140
the exterior angle=180-the interior angle=180-140=40
40 is the correct answer.
Answer:
4x^2-12x+9 is ur required ans
Step-by-step explanation:
area=6992m2
length=92m
Now,
area of rectangle=6992
12 is the diameter. We need the circumference which you get by multiplying 12x2 sides which = 24 which is the circumference
