A regular octagon rotates 360° about its center. How many times does the image of the octagon coincide with the preimage during

the rotation?

The number of times the image of the octagon will coincide with the preimage during rotation is determined by:
N = R/C

where
N is the number of times the preimage coincided with the rotated image during rotation
R is the angle of rotation
C is the central angle of the regular polygon

For an octagon, the central angle is
C = 360/8 = 45

So,
N = 360 / 45 = 8

Therefore, the rotated image of the octagon will coincide with the preimage 8 times during rotation.

Minchanka [31]

Answer:

2/3 min

Step-by-step explanation:

We can write these as equations

so 8-2.5x=5-0.5x

We isolate x by subtracting both sides by 5

3-2.5x=0.5x

add 2.5x to both sides

3=2x

divide both sides by 2

x=2/3min
