Answer:
a) Area of sector TRV = [tex] 42.4\: units^2 [/tex]
b) [tex] 0.8\: units[/tex]
Step-by-step explanation:
a)
In [tex] \odot R[/tex], TW is diameter.
Therefore,
[tex] m\widehat {TVW} = 180\degree [/tex]
[tex] \because m\widehat {TV} +m\widehat {VW} =m\widehat {TVW} [/tex]
[tex] \therefore m\widehat {TV} +120\degree =180\degree [/tex]
[tex] \therefore m\widehat {TV} =180\degree - 120\degree [/tex]
[tex] \therefore m\widehat {TV} = 60\degree [/tex]
[tex] \because m\angle TRV=m\widehat{TV} [/tex]
(Measure of central angle is equal to the measure of its corresponding arc)
[tex] \therefore m\angle TRV\:(\theta) =60\degree [/tex]
Radius (r) = RW = 9 units
Area of sector TRV
[tex] =\frac{\theta}{360\degree}\times \pi r^2 [/tex]
[tex] =\frac{60\degree}{360\degree} \times 3.14\times 9^2 [/tex]
[tex] =\frac{1}{6} \times 3.14\times 81 [/tex]
[tex] =\frac{1}{6} \times 254.34 [/tex]
[tex] =42.39\: units^2 [/tex]
Area of sector TRV[tex] =42.4\:units^2 [/tex]
b)
Length of [tex] \widehat{VW} [/tex]
[tex] =\frac{120\degree }{360\degree} \times 2\pi r [/tex]
[tex] =\frac{2}{3} \times 3.14\times 9 [/tex]
[tex] =2 \times 3.14\times 3 [/tex]
Length of [tex] \widehat{VW} [/tex] [tex] = 18.84\: units [/tex]
[tex] \overline{TW} =2*RW =2*9 = 18\: units[/tex]
[tex] \widehat{VW}- \overline{TW}= 18.84-18=0.84\: units[/tex]
[tex] \widehat{VW}- \overline{TW}= 0.8\: units[/tex]

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.

4 (10-x) = 8x + 4
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
3 = x

What is the approximate volume of the cone that is 9 cm in height and 15 cm as a radius use 3.14 for pi
Answers
Answer:
2120.58
Step-by-step explanation:
Answer:
The volume of a cone is pi multiplied by the radius squared times the height divided by three.
Step-by-step explanation:
If 3.14 is used for pi:
V = 3.14 * 15^2 (9/3)
= 3.14 * 15^2 (3)
= 3.14 * 225 * 3
= 706.5 * 3
= 2,119.5 cm cubed
If 3.14 is not used for pi:
V = pi * 15^2 (9/3)
= pi * 15^2 (3)
= pi * 225 * 3
= 706.8583470577035 * 3
= 2,120.57504117311 cm cubed

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

-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.
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.
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.
