Question

Trapezoid W′X′Y′Z′ ​ is the image of trapezoid WXYZ under a dilation through point C.

What scale factor was used in the dilation?

Answer 1

formula for scale factor
=image devide object
the answer is c

Answer 2

Option C.

Explanation:

Two trapezoids W'X'Y'Z' and WXYZ have been given in the figure attached.

Trapezoid WXYZ has been dilated to form another trapezoid W'X'Y'Z'.

We have to find the scale factor by which WXYZ was dilated.

Dilation factor =
`\frac{\text{Trapezoid W'X'Y'Z'}}{\text{Trapezoid WXYZ}} = (W'X')/(WX)`

=
`(6)/(8)`

=
`(3)/(4)`

Therefore,
`(3)/(4)` is the dilation factor by which trapezoid WXYZ was dilated.

Option C is the answer.
