Hi winsome, Each arc will have the same measure since the chords making up the regular pentagon are congruent. There are 360 degrees in a complete circle. Each arc is one-fifth of this measure. Each arc would then have to measure _____ degrees. Now, if you trying to find the arc length, you will need to know the circumference and we'll need to have the radius to do this.
