The first step to solve this problem is to formulate equations. Since the triangle has two equal sides, you can conclude that the angles adjacent to the sides are equal which means:
3x – 11 = 2x + 11
We can now solve for the value of x:
3x – 2x = 11 + 11
x = 22
The sum of the angles of a triangle is 180 so we can formulate another equation:
3x – 11 + 2x + 11 + 2y = 180
5x + 2y = 180
Remember that the value of x is 22 so you should substitute the value of x:
5(22) + 2y = 180
110 + 2y = 180
2y = 180 – 110
2y =70
y = 35

So (8x10) + (2x45) + (2x65) is the equation
And the answer is $300 because 8x10 is 80, 2x45 is 90, 2x65 is 130 and if you add it all up you'll get $300

Answers
[tex]\sf\dfrac{sin(X)}{x}=\dfrac{sin(Y)}{y}=\dfrac{sin(Z)}{z}[/tex]
We know what angle Y is and what side y is, so let's use that along with angle Z and side z:
[tex]\sf\dfrac{sin(Y)}{y}=\dfrac{sin(Z)}{z}[/tex]
Plug in what we know:
[tex]\sf\dfrac{sin(51)}{2.6}=\dfrac{sin(76)}{z}[/tex]
Multiply 'z' to both sides:
[tex]\sf\dfrac{sin(51)}{2.6}z=sin(76)[/tex]
Divide sin(51)/2.6 to both sides:
[tex]\sf z=\dfrac{sin(76)(2.6)}{sin(51)}[/tex]
Plug it into your calculator.

What is the perimeter of AEB
Answers
18.5 ft
Explanation:
part (a): getting the value of AE:
The two triangles AEB and DEF are similar. Therefore, we can make use of the similar proportionality as follows:
AE / DE = BE / FE
Now, we have:
AE is the unknown we want to find
DE = AE + 2
BE = 7.8 ft
FE = 7.8 + 2.4 = 10.2 ft
Substitute in the above relation and get the value of AE as follows:
AE / DE = BE / FE
AE / (AE+2) = 7.8 / 10.2
10.2 AE = 7.8 AE + 15.6
2.4 AE = 15.6
AE = 6.5 ft
Part (b): getting the perimeter of AEB:
perimeter = AE + EB + AB
perimeter = 6.5 + 7.8 + 4.2
perimeter = 18.5 ft

We have m = 3, [tex]x_1 = 5[/tex], and [tex]y_1 = 10[/tex].
We plug in these values to get
[tex]y-10=3(x-5)[/tex].
We now rearrange to get this into slope-intercept form, [tex]y=mx+b[/tex], by solving for y.
[tex]y=3(x-5)+10\\y=3x-15[/tex]
y = 3x - 5
Explanation:
The equation of the line in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept
We are given that the slope is 3. Therefore, the equation now is:
y = 3x + c
Now, we need to get the value of c. To do so, we will substitute with the given point (5,10) in the equation and solve for c as follows:
y = 3x + c
10 = 3(5) + c
10 = 15 + c
c = 10 - 15
c = -5
Based on the above, the equation of the line is:
y = 3x - 5

Canada is the king of the doughnut world, as it has more doughnut shops per capita than any other country in the world. Tim Hortons, the most popular doughnut joint in Canada, had 3660 locations in Canada in 2015. If the population of Canada was approximately 35.75 million citizens in 2015, what was the number of Tim Hortons stores per capita in Canada in 2015?
Express your answer in scientific notation rounded correctly to three decimal places.
Answers
Per capita means the number of schools per person. There are more people than stores, so the number must be lower than 1.
To find the rate, we divide the total number of stores by the population.
3660 / 35750000 = .0001024 = 1.024 x 10^-4
Answer:
Number of Tim Hortons stores per capita is [tex]1.024\times 10^{-4}[/tex]
Step-by-step explanation:
Canada is having more doughnut shops per capita than any other country in the world means availability of Horton's store per person are more.
Number of Hortons stores in Canada = 3660
Population of Canada in 2015 = 35.75 million
In scientific notation population = [tex]35.75\times 10^{6}[/tex]
Now stores per person = [tex]\frac{3660}{35.75\times 10^{6}}[/tex]
(To calculate stores per capita we will divide number of stores by population of Canada)
Stores per capita = [tex]102.377\times 10^{-6}=1.024\times 10^{-4}[/tex]
So the answer is [tex]1.024\times 10^{-4}[/tex]

15% of 280 is 0.15(280) = 42
This means the price was cut by €42.
