Answer:
Sum of the interior angles of the triangle is 180°.
According to the above problem,
[tex]4y + (y + 11) + 39 = 180 \\ 5y + 50 = 180 \\ 5y = 130 \\ y = \frac{130}{5} \\ \boxed{y = 26}✓[/tex]
y=26° is the right answer.Related Questions

Given;
The graph of a line.
To find:
The slope of the line.
Solution:
From the given graph it is clear that the line passes through the points (1,7) and (3,5).
So, the slope of the given line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{5-7}{3-1}[/tex]
[tex]m=\dfrac{-2}{2}[/tex]
[tex]m=-1[/tex]
Slope of the line is -1.
Therefore, the correct option is D.
The Fun Guys game rental store charges an annual fee of $5 plus $5.50 per game
rented.
The Game Bank charges an annual fee of $11 plus $2.50 per game.
For how many game rentals will the cost be the same at both stores?
Answers
Answer:
2 games
Step-by-step explanation:
Given data
The Fun Guys game
charges annual fee of $5 plus $5.50 per game
let the number of games be x
and the total charges be y
The expression for the total is
y=5+5.5x---------------1
The Game Bank
charges an annual fee of $11 plus $2.50 per game.
y=11+2.5x---------------2
Equate 1 and 2 above
5+5.5x=11+2.5x
collect like terms
5.5x-2.5x= 11-5
3x= 6
divide both sides by 3
x= 6/3
x= 2
It will take 2 games

Answer:
x = 12
Step-by-step explanation:
18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.
Using this 3:4 scale factor we can find the missing side x.
Solving for x :
[tex]\frac{3}{4}[/tex] × 16 = 12
x = 12
OR: Set up a proportion:
[tex]\frac{24}{16}[/tex] × [tex]\frac{18}{x}[/tex]
cross-multiply
16 × 18 = 288
24 × x = 24x
288 = 24x
x = 12

x+y=2
Answers
Y= X+8 X+Y=2
-x -x
Y= -x+2
Y=x+8
Y=-x+2
Y=10
Answer:
(-3,5)
Step-by-step explanation:
To solve using substitution, first isolate one variable in one of the given equations. Then, substitute the value you received from that equation for the matching variable in the second equation. Finally, substitute that value back into any of the equations to have both the x and y values.
1) The y in y = x + 8 is already isolated, so let's substitute that value for the y in x + y = 2. Substitute x + 8 for y in x + y = 2, then solve:
[tex]x + y = 2\\x + (x + 8) = 2 \\x + x + 8 = 2\\2x + 8 = 2 \\2x = -6\\x =-3\\[/tex]
Therefore, the x-value of the solution is -3.
2) Substitute the x value back into any of the one equations to find the value. Any choice is fine - in my work, I chose to substitute -3 for the x in y = x + 8:
[tex]y = x + 8 \\y = (-3) + 8\\y = -3 + 8\\y = 5[/tex]
Therefore, the y-value of the solution is 5.
3) Thus, the solution is (-3, 5).

Find the length AB ?
Answers
Answer:
AB = 54
Step-by-step explanation:
DE is a midsegment of the triangle and is half of AB , that is
2x + 13 = [tex]\frac{1}{2}[/tex](13x - 37) ← multiply through by 2 to clear the fraction
4x + 26 = 13x - 37 ( subtract 13x from both sides )
- 9x + 26 = - 37 ( subtract 26 from both sides )
- 9x = - 63 ( divide both sides by - 9 )
x = 7
Thus
AB = 13x - 37 = 13(7) - 37 = 91 - 37 = 54
Fay has a lemonade stand.
She spends £42 on ingredients.
She sells each glass of lemonade for £1.50.
If she sells 30 glasses of lemonade, what is her total profit?
Answers
Answer:
her total profit is 3
Step-by-step explanation:
1.50 x 30 = 45
to find total profit - 45-42= 3
£1.50 multiplied by 30 glasses equals £45
You then subtract £45-£42 to get £3 profit.

I can't find x y or z
Answers
Answer:
x = 4[tex]\sqrt{3}[/tex]
y = 6
z = 8
Step-by-step explanation:
keep in mind I'm not doing that well with geometry so this might all be wrong lol
x is part of a 30 60 90 triangle.
so x is 4[tex]\sqrt{3}[/tex]
next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.
4 + 6 = 10
10^2 = 100
100 = a^2 + b^2
y = 6 and z = 8 bc 36 + 64 = 100

Question : Find the derivative with respect to x of each of the following:
(see image)
Answers
Answer:
see explanation
Step-by-step explanation:
Note that [tex]log_{e}[/tex] x = lnx ( natural logarithm)
Using the standard derivatives
[tex]\frac{d}{dx}[/tex] (lnx ) = [tex]\frac{1}{x}[/tex] , [tex]\frac{d}{dx}[/tex] ([tex]log_{a}[/tex] x ) = [tex]\frac{1}{xlna}[/tex]
Using the chain rule
Given y = f(g(x)) , then
[tex]\frac{dy}{dx}[/tex] = f'(g(x))) × g'(x) ← chain rule
(c)
y = [tex]log_{10}[/tex] (x² - 2) then
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{(x^2-2)ln10}[/tex] × [tex]\frac{d}{dx}[/tex] (x² - 2)
= [tex]\frac{1}{(x^2-2)ln10}[/tex] × 2x
= [tex]\frac{2x}{(x^2-2)ln10}[/tex]
(d)
y = ln([tex]\frac{1}{x}[/tex] )
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{\frac{1}{x} }[/tex] × [tex]\frac{d}{dx}[/tex] ([tex]x^{-1}[/tex] )
= x × - [tex]x^{-2}[/tex]
= x × [tex]\frac{-1}{x^2}[/tex]
= - [tex]\frac{1}{x}[/tex]
