The operation above rotates the regular pentagon clockwise by (72n) degrees from its center. What replaces the initial b position when n = 4?

A. a

B. b

C. c

D. d

E. e

Kudos for a correct solution.The central Angle will be divided in to 5 equal parts when all vertices are joined with the centre of the Pentagon

Therefore Each angle = 360/5 = 72 Degree

i.e. When the Pentagon Rotates by 72 degrees then A replaced the Point B

i.e. When the Pentagon Rotates by 72*2 degrees then E replaced the Point B

i.e. When the Pentagon Rotates by 72*3 degrees then D replaced the Point B

i.e. When the Pentagon Rotates by 72*4 degrees then C replaced the Point BAnswer: Option C
