The quadrilateral shown is a rectangle. What is the measure of CE?

|CE|=2

Step-by-step explanation:

The quadrilateral is shown in the attachment

Recall that the diagonals of a rectangle are congruent.

This implies that:

|AC|=|BD|

We substitute the expressions to get:

This is now a linear equation in one variable.

Group similar terms to get:

Simplify to get:

15=3x

Divide both sides by 3 to get:

Recall again that the diagonals of a quadrilateral bisect each other.

Plug x=5
