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

aalyn [17]

Answer:

|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:

$2x-6=5x-21$

This is now a linear equation in one variable.

Group similar terms to get:

$-6+21=5x-2x$

Simplify to get:

15=3x

Divide both sides by 3 to get:

$5=x$

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

$|CE|=\frac{1}{2}|AC|$

$|CE|=\frac{1}{2}|2x-6|$

Plug x=5

$|CE|=\frac{1}{2}|2*5-6| =10-6=\frac{1}{2}*4=2$

Answer:

The circumference is approximately 125.66.

Step-by-step explanation:

The formula for circumference is 2 x 3.14(r). Radius (or r) in this case is equal to 20 since the diameter is two times the length of the radius. 40/2 = 20.

2 x 3.14(20) ≈ 125.66
