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

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

m of segment AB is 8

m of segment AC is 17

thus the sine of

alexdok [17]

If you would like to know what percent of 100 is 30, you can calculate this using the following steps:

x% of 100 is 30
x% * 100 = 30
x/100 * 100 = 30
x = 30%

The correct result would be a. 30%.
