Find the angle of rotation about the center of the regular pentagon that maps a to d.
a.) 216 degrees
b.) 72 degrees
c.) 288 degrees

216

add 72 three times and you get the answer

Step-by-step explanation:

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
