Step-by-step explanation:
Your answer is correct. The mean distance is half of the length of the major axis. So a = 58 million miles.
Answer:
0.9775
(n-2)×180=3420
180n-360=3420
180n=3420+360
180n=3780
n=3780/180
n=21
that is, the number of sides is 21
to get the size of each exterior angle=
360/21
=17.14°
