<h3>Answer: 10.1 cm approximately</h3>

=====================================================

Explanation:

The double tickmarks show that segments DE and EB are the same length.

The diagram shows that DB = 16 cm long

We'll use these facts to find DE

DE+EB = DB

DE+DE = DB

2*DE = DB

DE = DB/2

DE = 16/2

DE = 8

-------------

Now let's focus on triangle DEC. We just found the horizontal leg is 8 units long. The vertical leg is EC which is unknown for now. We'll call it x. The hypotenuse is CD = 9

Use the pythagorean theorem to find x

a^2+b^2 = c^2

8^2+x^2 = 9^2

64+x^2 = 81

x^2 = 81 - 64

x^2 = 17

x = sqrt(17)

That makes EC to be exactly sqrt(17) units long.

If you follow those same steps for triangle ADE, then you'll find the missing length is AE = 6

---------------

So,

AC = AE+EC

AC = 6 + sqrt(17)

AC = 10.1231056256177

AC = 10.1 cm approximately

Y axis is counting by 2's
it started at 2 and went up to 6
Y = 4

X axis is counting by 2'2
starts at one goes to 3
X = 2

Slope is 4/2 because rise over run
4/2 = 2
Slope is simplified to 2.

One angle of atriangle measures 12 degrees. the second angle's measurements is five times the third. what is the measure of the
andrezito [222]
28 degrees. This is because the first angle is 12 degrees, the third is x degrees and the second is 5x. You know that in a triangle the angles add up to 180 degrees so 12 + 5x + x = 180. Then you get 6x =168 and x =28 degrees. (**x being the thrid angle**)

Madison made the following table to record the height of each person in her family.
alexira [117]
By taking the height of the dad and mom 6²3/8 minus 5²5/8
We can separate the 6² and 5², which will give us 1² then look at the 3/8 minus the 5/8, this equals 2/8, which is 1/4. So the difference is 1²1/4

How to solve 4x-c=k solve for x
Tresset [83]

Answer:

x = \frac{k + c}{4}

Step-by-step explanation:

<em><u>Given:</u></em>

4x - c = k

<em><u>Solve for:</u></em>

x

<em><u>Solution:</u></em>

(1) Let's move all of components that do not contain x (our target) to the right side (notice the change of sign of c from negative to positive):

4x = k + c

(2) Let's divide both sides of equation by 4:

\frac{4x}{4}  = \frac{k + c}{4}

(3) Now, we simplify the left side:

x = \frac{k + c}{4}

This is the solution.

Hope this helps!

:)
