leo designs a piece of jewelry in the shape of a regular pentagon. each side of the object measures 3 centimeters. leo photographs the object, enlarges it so that the sides each measure 8 centimeters, and prints the photo. what scale factor did leo use to create the photograph from the original?
A. 2 1/3
B. 2 2/3
C. 3.8
D. 11
To find the scale factor, divide the length of the enlarged side by the length of the original side.
Enlarged side length: 8 centimeters
Original side length: 3 centimeters
Scale factor = Enlarged side length / Original side length
Scale factor = 8 / 3
Scale factor ≈ 2.6667
