Which best explains why all equilateral triangles are similar?
all equilateral triangle’s can be mapped onto each other using dilations
all equilateral triangle can be mapped onto each other using rigid transformations
all equilateral triangles can be mapped onto each other using combinations of dilations and rigid transformations
all equilateral triangles are congruent and therefore similar with side links and a 1:1 ratio
Answer:
D
Step-by-step explanation:
I hope this helps you out!
Answer:
all equilateral triangle’s can be mapped onto each other using dilations.
Step-by-step explanation:
Because you can dilate or increase the size and scale the triangle about a certain point so if you do it correctly, this can be done with just a dilation.
Also an equilateral triangle is defined as a triangle where all the sides are congruent in length. This does not mean that all equilateral triangles are congruent (Do not get confused with D) to each other since size is the undefined variable so all equilateral triangles are proportional which means that they always have a ratio between them depending on the scale factor.
For example, let's say I have an equilateral triangle with a side length of 2, this means that all the sides must have a length of 2, but I can also have an equilateral triangle with a side length of 3, which means that all the sides will have that length for that triangle.
2 ≠ 3, but there is always a conversion factor between the side lengths. In this case a scale factor of 3/2 from the triangle with a side length of 2 to the one with a side length of 3. And a scale factor of 2/3 going from the triangle with a side length of 3 to the triangle with a side length of 2. Because all the sides are congruent, the angles must all be 60° degrees because individual side proportions defined by trigonometry are based on angles and sides. Thus, the angles are also affected due to the change in ratio.

x² = 30² +21² -2(30)(21) Cos 123°
Answer:
x ≈ 44.69
Step-by-step explanation:
x² = 30² +21² -2(30)(21)Cos123°
x² = 900 + 411 - 1260cos123°
x² = 1311 - 1260cos123²
~Take square root of both sides
x = √1997.245184111

Brenda and Shayna are selling flower bulbs for a school fundraiser. Customers can
buy bags of windflower bulbs and packages of crocus bulbs. Brenda sold 5 bags of
windflower bulbs and 5 packages of crocus bulbs for a total of $145. Shayna sold 3
bags of windflower bulbs and 5 packages of crocus bulbs for a total of $121. Find
the cost of one bag of windflower bulbs.
Given :
Customers can buy bags of windflower bulbs and packages of crocus bulbs. Brenda sold 5 bags of windflower bulbs and 5 packages of crocus bulbs for a total of $145.
Shayna sold 3 bags of windflower bulbs and 5 packages of crocus bulbs for a total of $121.
To Find :
The cost of one bag of windflower bulbs.
Solution :
Let, cost of one bag of windflower bulbs and crocus bulbs is x and y.
Converting given statement to mathematical equation, we get :
5x + 5y = 145
x + y = 29 ...1)
and
3x + 5y = 121 ...2)
Solving equation 1 and 2, we get :
3( 29 - y ) + 5y = 121
87 - 3y + 5y = 121
2y = 34
y = 17
and x = 12
Therefore, cost of one bag of windflower bulbs is $12 .
Hence, this is the required solution.
A holiday costs £1900. Work out the
price after a 9% discount.
Answer:
$1729
Step-by-step explanation:
[tex]\frac{100-9}{100} * 1900[/tex]
Answer:
1729
Step-by-step explanation:
1900 divided by 100 is 19
1% equals 19
1 times 9 equals 9
19 times 9 equals 171
171 = 9%
171 - 1900 = 1729
price after a 9% discount is 1729

In △XYZ, suppose XY < XZ. Which inequality relates two angles in △XYZ?
Answer:
m∠Z < m∠Y
Step-by-step explanation:
m∠Z < m∠Y
The inequality that relates the two angles in triangle XYZ is m∠Z < m∠Y
From the question, we have:
Triangle XYZSide length XY is less than side length XZThis means that, the angle at point Y is greater than the angle at point Z
i.e. m∠Y > m∠Z
Rewrite the inequality as:
m∠Z < m∠Y
Hence, the inequality that relates the two angles in triangle XYZ is m∠Z < m∠Y

Prove that sin(3x)/sin(x)·cos(x) = 4cos(x)-sec(x)
Here is a huge hint:
sin(3x) = 3 sin (x) - 4(sin x)^3
sec (x) = 1/sin(x)
Take it from here.
The expression {4 cos(x) - sec(x)} is equivalent to {sin(3x)/sin(x) cos(x)} is proved below.
What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the equation -
sin(3x)/(sin(x)·cos(x)) = 4cos(x) - sec(x)
We have the following equation -
{sin(3x)/(sin(x)·cos(x)} = 4cos(x) - sec(x)
Now, we know -
sin3x = 3 sin x - 4 sin³x
So, we can write -
(3 sin x - 4 sin³x)/(sin(x)·cos(x) = 4cos(x) - sec(x)
sin(x) (3 - 4sin²x) / sin(x) cos(x) = 4cos(x) - sec(x)
(3 - 4sin²x)/cos(x) = 4cos(x) - sec(x)
(3 - 4sin²x) = cos(x){4 cos(x) - 1/cos(x)}
(3 - 4sin²x) = 4cos²x - 1
3 + 1 = 4cos²x + 4sin²x
4 = 4(cos²x + 4sin²x)
4 = 4
1 = 1
LHS = RHS
Therefore, it is proved that the expression {4 cos(x) - sec(x)} is equivalent to {sin(3x)/sin(x) cos(x)}.
