Answer:
Option C.
Step-by-step 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 =
=
=
Therefore, is the dilation factor by which trapezoid WXYZ was dilated.
Option C is the answer.

Answer:
Step-by-step explanation:
Given
Let the three sides be a, b and c
Such that:
Required
Find c such that a, b and c do not form a triangle
To do this, we make use of the following triangle inequality theorem
To get a valid triangle, the above inequalities must be true.
To get an invalid triangle, at least one must not be true.
Substitute:
The results of the inequality is: and
Rewrite as: and
This means that, the values of c that make a valid triangle are 1 to 9 (inclusive)
Any value outside this range, cannot form a triangle
So, we can say:
, since no options are given
