Question

how do find the measure of the angle formed by a) two consecutive radii?? when you have a pentagon??

Answer 1

If the pentagon is regular, then two consecutive radii form a central angle of the regular pentagon.

The five central angles sum to 360 and are congruent.

Divide 360 by 5 to get the measure of one central angle.
