Answer:
The first statement is true because they have congruent angles.
The side length does not matter here because it's useless unless you're trying to find the perimiter of a triangle, which has a completely different algorithm. It is called the Pythagorem Theorum.

Two health clubs offer different pricing plans for their members. Both health clubs charge a one-time sign-up fee and a monthly membership fee. The graph below represents what Health Club B charges.
The equation of line is solved and Health Club B costs $ 7 less in monthly membership fees that Health Club A
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 3 , 106 )
Let the second point be Q ( 6 , 187 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 187 - 106 ) / 3
Slope m = 27
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 106 = 27 ( x - 3 )
y - 106 = 27x - 81
Adding 106 on both sides , we get
y = 27x + 25 be equation (1)
Now , let the equation of line be represented as B
And , the value of B is
Let the first point be R ( 3 , 105 )
Let the second point be S ( 6 , 165 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 165 - 105 ) / 3
Slope m = 20
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 105 = 20 ( x - 3 )
y - 105 = 20x - 60
Adding 105 on both sides , we get
y = 20x + 45 be equation (2)
Now , when x = 1
Substitute the value of x = 1 in equation (1) and equation (2) , we get
y₁ = 27 + 25 = $ 52
y₂ = 20 + 45 = $ 65
So , health club B costs $ 7 less than health club A every month
Hence , the equation of lines is solved

What word can be used to describe the distribution of this data set: 5, 4, 10, 3, 3, 4, 7, 4, 6, 5, 11, 9, 5, 7. *
Ungrouped data
Tabular data
Central Tendency
Grouped data
Answer:
Ungrouped data
Step-by-step explanation:
The ungrouped data is the data where it has only individual data points that means it does not have a frequency distribution
So according to the given situation
Since it is mentioned that , 4, 10, 3, 3, 4, 7, 4, 6, 5, 11, 9, 5, 7 so this represent the ungrouped date
The nth term of the sequence is n^2 + 20
How many terms in the sequence are less than 50
plss help!!
Answer: 5 terms.
Step-by-step explanation:
We know that the n-th term of a sequence is:
Aₙ = n² + 20
Where n can be any natural number, then n ∈ {1, 2, 3, ...}
We want to find how many terms are smaller than 50.
Then we could find the first value of n such that Aₙ is equal or larger than 50.
Then we can solve:
Aₙ = n² + 20 = 50
then:
n² = 50 - 20 = 30
n = √30 = 5.48
This is not a natural number, so we need to round to the next one that is n = 6
This means that the first natural number n such that Aₙ is equal or larger than 50 is n = 6, then for the values:
n = 1, 2, 3, 4, 5
Aₙ is smaller than 50
This means that there are 5 terms of the sequence that are smaller than 50.

Are 1/2x+3/4-5/8x-7/8 and 1/8(x+1) equivalent expressions? show your work.
No, 1/2x+3/4-5/8x-7/8 and 1/8(x+1) are not equivalent expressions.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
The given expression is 1/2 x+3/4-5/8 x-7/8
Now, 1/2 x-5/8 x+3/4-7/8
-1/8 x- 1/8
-1/8(x+1)

There is no limit to how many figures you can create. There is not enough information to solve this. If this is only a part of the question, try to include all of it.
Answer: I disagree. If Pablo has enough time to make 10 figures. He could make 8 of the large figures and make $80.00 and then make 2 of the large figures and make $16. Together with the 8 small and 2 large figures they would make $96.00

Write the sum as a product.
sin(x)-sin(4x)
Step-by-step explanation:
Given
sin(x) - sin(4x)
= 2 cos (( x + 4x)/2) * sin ( ( x - 4x) / 2))
= 2 cos 5x/2 • sin -3x / 2
= - 2 cos 5x/2 • sin 3x/2
Hope it helps :)❤
The sum sin(x) - sin(4x) can be written as a product as 2 sin (5x/2) cos (3x/2).
What are Trigonometric Ratios?Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.
The main three trigonometric ratios are sine, cosine and tangent functions.
We have the trigonometric formula that,
sin A - sin B = 2 sin ([tex]\frac{A+B}{2}[/tex]) cos ([tex]\frac{A-B}{2}[/tex])
Here the sum is, sin(x) - sin(4x) where A = x and B = 4x.
sin(x) - sin(4x) = 2 sin ((x+4x)/2) cos ((x-4x)/2)
= 2 sin (5x/2) cos (-3x/2)
We also have, cos(-x) = cos(x).
So, sin(x) - sin(4x) = 2 sin (5x/2) cos (3x/2)
Hence the product form is sin(x) - sin(4x) = 2 sin (5x/2) cos (3x/2).

A system of linear equations has no solution when the equations describe parallel lines. Parallel lines have the same slope. In your equation, the slope is the x-coefficient, 8. A parallel line will have a slope of 8.
The second equation will have a slope of 8 if the system has no solution.
