Answer:
angle a is 116 degrees
Step-by-step explanation:
ok so first we have to make everything equal to 180 because every triangle is 180 degrees so it would be written like this:
(14x + 4) + (5x - 1) + (2x + 9) = 180
Then, we solve for x and x equals 8
After this we plug 8 back into the angle so it would be written like this:
14(8) + 4
This equals 116 degrees.
Answer:
116
Step-by-step explanation:
21x + 12 = 180
-12 -12
21x = 168
÷21 = ÷21
x = 8
14 x 8 + 4
112 +4
116

you wanna start by plugging in what you know.

now simplify.
a^2+4,225=9,025
[subtract 4,225 from both sides]
a^2=4,800
get a by itself by doing the opposite. [square root both sides]
a=69.28

If △ABC∼△LMN and △LMN∼△XYZ, is △ABC∼△XYZ? Use the AA similarity criterion to support your answer.
Answers
Answer:
yes because transitive property
Step-by-step explanation:
if abc~lmn, then the angles a and b are similar to angles l and m. and if lmn~xyz then angles l and m are similar to angles x and y. therefore, using transitive property, angles a and b would be similar to angles x and y. so using AA similarity, the two triangles would be similar

What is x?
Answers
Answer:
3 = x
Step-by-step explanation:
4 (10-x) = 8x + 4
Distribute
40 -4x = 8x+4
Add 4x to each side
40 -4x+4x = 8x+4 +4x
40 = 12x+4
Subtract 4
40 -4 = 12x+4-4
36 = 12x
Divide each side by 12
36/12 = 12x/12

Whats the slope form?
Answers
Answer:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
Answer is Ax+By=C. ... A, B, C are integers (positive or negative whole numbers)
Step-by-step explanation:
Plz mark brainliest
Step-by-step explanation:
I'm assuming you mean Point- Slope Form of a linear equation.
If so, then a point slope form of a linear equation is one that looks something like this:
y - y₁ = m (x - x₁)
where (x₁, y₁) is a point on the line and m is the gradient of the line.

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.

-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

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.

n must be used in your proof.

= 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.
