Question

what is the measure of one of the exterior angle of the regular decagon

Answer 1

Since a regular hexagon has 10 sides, you can find the measure of each exterior angle with the formula E = 360/ n.

E means exterior angle, and n means number of sides, this formula can be applied to any regular polygon too! In these cases you just divide 360 by the number of sides said polygon has.

Therefore, the measure of each exterior angle for a regular decagon is 36 degrees!
