find the value of x and please show how

Answers

Answer:

?=91 degrees.

Step-by-step explanation:

There is no x- I'll find ? though.

So, angles in a triangle must equal 180.

180-29-62=89. The last angle in the triangle is 89 degrees.

A straight angle is equal to 180 degrees. ? + 89=180.

180-89=91.

?=91 degrees.

the answer is 0.08333333333

Answer:

I don't completely understand your question but the answer is 0.8333333333

Step-by-step explanation:

When you said 1/2 I assumed you meant fraction, so I turned 1/2 into a fraction which is 0.5. Then I divided 0.5 by 6 on a calculator and that is how I got my answer.

What is the slope between (2,1); (5,9)

Answers

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

Answer:

[tex]\frac{8}{3}[/tex]

Step-by-step explanation:

(2, 1)

(5, 9)

Find the slope

____________

When finding slope, we always have to follow the formula :

[tex]\frac{y^2-y^1}{x^2-x^1}[/tex]

The y in the fraction are the second number within the coordinate points, while the exponents are the second number from the second point and the first number from the first point. The same goes for x. Therefore substitute x and y with their corresponding values :

[tex]\frac{9-1}{5-2}[/tex]

[tex]\frac{8}{3}[/tex]

n is the middle integer of three consecutive positive integers.
The three integers are multiplied to give a product.
n is then added to the product.
Prove that the result is a cube number.
n must be used in your proof.
Your final line must consist of only,
= n^3

Answers

Answer :

[tex]\boxed{\textsf{ The final answer is \textbf{n}$^{\textbf{3}}$ .}}[/tex]

Step-by-step explanation:

Its given that n is the middle out of the three consecutive integers . So ,

The last integer will be :-

[tex]\sf\implies Last \ Integer \ = \ n - 1 [/tex]

The next Integer will be :-

[tex]\sf\implies Next \ Integer \ = \ n + 1 [/tex]

Now the Question says that the three integers are multipled to give a product . So that would be.

[tex]\sf\implies Product_{(three\ consecutive\ integers)}= (n-1)n(n+1) = (n^2-1)(n) = \pink{n^3-n}[/tex]

Now thirdly it's given that n is added to the given integer . That would be ,

[tex]\sf\implies Adding\ n = \ n^3 - n + n = \pink{n^3} [/tex]

Here - n and +n gets cancelled. So we are ultimately left out with n³.

Hence the final number is a cube of some number.

Step-by-step explanation:

-First you want to find side CD:

. Draw a line from point C directly down to make a right angled triangle (you can lable the extra point whatever letter you want but for this explanation it's gonna be x)

. You know that CX will be 16.7cm because its the same length as BA

. To find CD you need to use SOH,more specifically the hypotenuse using SOH

. H=O/S (O=16.7, S= sin(43))

.put this in your calculator and you'll get CD=24.4868624 (don't round yet)

-now you wanna find AD but more specifically XD because that's the little part you don't know:

. Using the same triangle from earlier, we use CAH now to find A (aka XD)

. A=C*H (C=cos(43), H=24.4868624 (the value of H/CD from the previous calculation)

. That should give you: 17.90855746

. You're still not done, do 17.90855746+21.2=39.10855746 (this is your value for AD

-add all your values now:

39.10855746+24.4868624+16.7+21.2=101.4954199

-now round to 3 significant figures:

101.4954199 -> 101cm

The perimeter is 101cm

Which equation is correct regarding the measure of ZMNP? O MZMNP = {(x - y) MLMNP = {(x + y) O MZMNP = {(z + y) O MZMNP = {(z-Y)​

Answers

Step-by-step explanation:

It was correct on edge 2021

The equation that is correct regarding the measure of <MNP is 1/2(x-y)

Circle geometry

In order to determine the measure of m<MNP, we will use the theorem shown below;

The angle at the vertex is half the difference of angles at the intercepted arcs.

The angle at the vertex = m<MNP

angle a the arcs are x and y

Hence;

m<MNO = 1/2 (x - y)

Hence the equation that is correct regarding the measure of <MNP is 1/2(x-y)
