<span>Given:
m∠BAC = 46° (angle a)
m∠CBA = 54° (angle b)

It is also given that AB is parallel with CD, so that means the points on AB is the same with the points on CD ( corresponding angles).

So ECD=BAC=45 and EDC=CBA=54

And the sum of the interior angle of a triangle is 180 degrees so we can work out that,

46+54+ angle DEC=180
</span>angle DEC=180-46-54
angle DEC=80

If ABCD is a square and AB = 10, what is the measure of CE to the nearest hundredth?

andrey2020 [161]

Answer:

$AC=14.14\ units$

Step-by-step explanation:

<em><u>The correct question is </u></em>

If ABCD is a square and AB = 10, what is the measure of AC? (rounded to the nearest hundredth)

see the attached figure to better understand the problem

we know that

All four sides of the square are congruent and all four interior angles are equal to 90°.

so

AB=BC=CD=AD

In the right triangle ACD

Applying the Pythagorean Theorem

$AC^2=CD^2+AD^2$

we have that

$CD=AD=AB=10\ units$

substitute the given value

$AC^2=10^2+10^2$

$AC^2=200$

$AC=\sqrt{200}\ units$

$AC=14.14\ units$

A commercial laundry charges $5.25 per load. You have $31.50. Write and solve an inequality to find the greatest number of loads

4vir4ik [10]

Charges per load = $5.25

Total money = $31.50

As the situation says that charges are 5.25 and one has a total money of 31.50 so lets suppose the total load one has be 'w'

so equation becomes:

$5.25w\leq31.50$

solving it we get, $w\leq6$

So, option C is the correct answer.
