Octagon abcdefgh and its dilation, octagon a'b'c'd'e'f'g'h', are shown on the coordinate plane below: octagon abcdefgh with ordered pairs at a at 3, 1, at b 3, negative 1, c 1, negative 3, d negative 1, negative 3, e negative 3, negative 1, f negative 3, 1, g negative 1, 3, h 1, 3. octagon a prime b prime c prime d prime e prime f prime g prime h prime with ordered pairs a prime 6, 2, at b prime 6, negative 2, at c prime 2, negative 6, at d prime negative 2, negative 6, at e prime negative 6, negative 2, at f prime negative 6, 2, at g prime negative 2, 6, at h prime 2, 6 if the center of dilation is at the origin, by what scale factor was octagon abcdefgh dilated?

From the coordinates given we can make out that dilaton is having a scale factor of 2.

Explanaton:

A = (3,1):    A' =(6,2)

B = (3,-1)  :  B' = (6,-2)

C = (1,-3):    C' = (2,-6)

D = (-1,-3):   D'=(-2,-6)

E =(-3, -1):  E'= (-6,-2)

F = (-3,1):   F'=(-6,2)

G = (-1,3)  :  G' = (-2,6)

H = (1,3):   H' = (2,-6)

We find that all the coordinates have become doubled as that of original.

Let us find length of AB :

AB = distance between A and B =2 units

A'B' = distance between A' and B' =4 units

i.e. length increased by a scale factor of 2

Hence dilation with scale factor 2.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
