Quadrilateral ABCD is rotated 50 degrees about point R to create quadrilateral A' B' C' D'. What is the length of segment C' D'?

Answer:
CD = 2.8
Step-by-step explanation:
Quadrilateral ABCD is rotated to create Quadrilateral A'B'C'D' only. It is not dilated so all of its sides will be equal.
So,
CD = C'D'
Given that C'D' = 2.8
So,
CD = 2.8
