Find BC
The sum of [tex]angles\ at\ a\ point[/tex] is 360.
So:
[tex]7n + 12 + 13n - 16 + 6n = 360[/tex]
Collect like terms
[tex]7n + 13n + 6n = 360 + 16 - 12[/tex]
[tex]26n = 364[/tex]
Solve for n
[tex]n = 364/26[/tex]
[tex]n = 14[/tex]
From the circle:
[tex]BC = 6n[/tex]
Substitute 14 for n
[tex]BC = 6*14[/tex]
[tex]BC = 84[/tex]

A right square pyramid has a base with sides that are 2 inches in length and a slant height of 7 inches. If the lengths of the sides of the base and the slant height are multiplied by 7, by what factor is the surface area multiplied? A. 7 B. 14 C. 28 D. 49
Answer:
Step-by-step explanation:
base b = 2 in
slant height L = 7 in
lateral area = 4·½bL = 4·½·2·7 = 28 in²
base area = b² = 4 in²
surface area = 28+4 = 32 in²
If b = 14 and L = 49:
lateral area = 4·½·14·49 = 1372 in²
base area = 196 in²,
and surface area = 1372+196 = 1568 in²
The surface area has multiplied by 49.
Answer:
49

In ΔRST, the measure of ∠T=90°, the measure of ∠R=67°, and TR = 94 feet. Find the length of RS to the nearest tenth of a foot......
Answer:
240.6 ft is your answer of your question.
Answer:
240.6 feetStep-by-step explanation:
to understand thisyou need to know about:trigonometryPEMDASlet's solve:to find x we will use cos function
[tex] \quad \: \cos( \theta) = \dfrac{adj}{hypo} [/tex]
substitute the value of [tex]\theta[/tex] and adj:
[tex] \quad \: \cos( {67}^{ \circ} ) = \dfrac{94}{x} [/tex]
cross multiplication:
[tex] \quad \: x\cos(67^{\circ})= 94 [/tex]
divide both sides by cos(67°) :
[tex] \quad \: \dfrac{x \cos( {67}^{ \circ} ) }{ \cos( {67}^{ \circ} ) } = \dfrac{94}{ \cos( {67}^{ \circ} ) } \\ \therefore \: x = 240.6[/tex]

The measure of ⏜ is 161°, and the measure of ⏜ is 107°.
What is the measure of ∠ ?
Answer:
m<AEB = 46°
Step-by-step explanation:
Given:
Arc AD = 161°
Arc BC = 107°
Required:
m<AEB
Solution:
Vertex angle = ½(sum of intercepted arcs) => Theorem for angle inside a circle and its intercepted arcs)
This:
m<AED = ½(AD + BC)
m<AED = ½(161 + 107) => Substitution
m<AED = ½(268) = 134°
✔️m<AEB = 180° - m<AED => Linear pair theorem
m<AEB = 180° - 134° => substitution
m<AEB = 46°
Solve for x based on the following system of equations:
x + y = 5
2x + 3y = 20
-10
-5
-2
5
10
Answer:
x = -5
Step-by-step explanation:
x + y = 5 can be also written as 3x + 3y = 15 by times 3 on both side, let it be equation (1), then let 2x + 3y = 20 be equation (2), then use equation (2) - (1), can get (2x - 3x) + (3y - 3y) = 20 - 15 ---> -x = 5, then x = -5.

Answer:
I'm not sure
I think its 30 or 26
Step-by-step explanation:
Answer:
30 feet
Step-by-step explanation:
The ladder laying against the wall will create a right triangle.
The side lengths will be 18 and 24 and you will solve for the hypoteneuse which will be the length of the latter.
You can use the pythagorean theorm so

Will mark brainliest hi! Pls answer only if you know <3
Answer:
(6, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + y = 11 → (1)
[tex]\frac{1}{2}[/tex] x - 5y = 8 ← (2)
Multiplying (2) by - 4 and adding to (1) will eliminate the x- term
- 2x + 20y = - 32 → (3)
Add (1) and (3) to eliminate x
0 + 21y = - 21
21y = - 21 ( divide both sides by 21 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
2x - 1 = 11 ( add 1 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
solution is (6, - 1 )

Answer:
Look below.
Step-by-step explanation:
From looking at this figure we could break it up into 3 different shapes and find the area of each giving us the area of the shape by adding.
Area of a square formula: A=LW
Area of a triangle formula: A=1/2bh
Rectangle:
A=8 x 4
A=32
Triangle 1:
A=1/2bh
A=1/2(3)(2)
A=3
Triangle 2:
A=1/2bh
A=1/2(3)(3)
A=4.5
Now add them all together to get your area of the figure.
32+3+4.5=39.5
Area=39.5
Crystal earns $5.50 per hour mowing lawns.
a. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
b. How much does Crystal earn if she works 3 hours and 45 minutes?
m(h) = 5.50h; $18.98
m(h) = [tex]\frac{h}{5.50}[/tex]; $0.68
m(h) = 3h + 45; $61.50
m(h) = 5.50h; $20.63
Answer:
For this case, the first thing we must do is define a variable:
h: number of hours worked.
We now write the equation that models the problem:
So, for 3 hours and 45 minutes we have:
Remember that we have the following conversion:
1 hour = 60 minutes
Substituting values:
Answer:

Francesca is growing 1/2 inch in each year. How many years will it take for her to grow 6 inches
Answer:
The number of years it will take for Francesca to grow 6 inches is 12 years
Step-by-step explanation:
The height to which Francesca is growing, Δh/Δt = 1/2 inch per year
The number of years, 'Δt', it will take her to grow 6 inches given as follows;
Δh/Δt = 1/2 inch/year
Δh = 1/2 inch/year × Δt
When Francesca grows 6 inches, we have;
Δh = 6 inches
∴ Δh = 6 inches = 1/2 inch/year × Δt
6 inches = 1/2 inch/year × Δt
Δt = 6 inches/(1/2 inch/year) = 12 years
The number of years it will take for Francesca to grow 6 inches, Δt = 12 years

Can the sides of a triangle have lengths 3, 16, and 19?
The answer is no. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.
Answer:
No
Step-by-step explanation:
Because you have to add the smallest ones which are 3 and 16 if u add them up it = 19 and you cant have 19 , 19 you have to have the smallest numbers ADD UP Greater Than the biggest number, when its equal to itself it doesn't form a triangle because the lengths are short by 1 please tell me if u need more help
