Question

what is the measure of each exterior angle in a regular pentagon?

Answer 1

The inner angle is \(360/5 = 72\) so the exterior angel is \(180- 72 = 108\).

Answer 2

exterioirs are supplements to the .... base angle for lack of a better term..

Answer 3

180 - 108 = exterior angle right?

Answer 5

72+72+108 from the definition maybe

Answer 6

What I know as exterior angle is:

So according to your definition the answer would be \(180+72 = 252\) instead, yes.

Answer 7

Answer 8
