In the diagram, triangle QRS is congruent to triangle XYZ. Find the measure of angle R.
Answer:
the correct answer is C. 75°
The value of ∠R = 75⁰
What are congruent triangles?The measurements of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of their corresponding sides and angles are equal, two triangles are said to be congruent.
Given ΔQRS ≅ ΔXYZ
for congruency the sides and angle of both the triangles should be equal so for ΔQRS and ΔXYZ ; QR = XY, QS = XZ, and RS = YZ and
∠Q = ∠X, ∠S = ∠Z and ∠R = ∠Y
from figure ∠Q = ∠X = 55⁰, ∠S = ∠Z = 50⁰
sum of angle of triangle is 180⁰,
∠Q + ∠S + ∠R = 180⁰
∠R = 180 - 55 - 50
∠R = 75⁰
Hence ∠R = 75⁰

Step-by-step explanation:
☆Well, we simply use the distance formula, which is:
[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]
...
☆All we need to do is plug in!
[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16[/tex]

Which equation has a graph parallel to the graph of 9x + 3y =22?
Answer:
y = -3x + 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = 22 in the form y = mx +c.
9x+3y = 22
3y = -9x +22
y = -3x + 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.

Given the Vertex (1,0) and the Directrix y = -¼, find the equation of the quadratic
(x - 1)2
(x + 5)2
2(x - 1)2
-x2 - 1
Answer:
y = (x - 1)²
Step-by-step explanation:
A parabola is the locus of a point such that its distance from a fixed point (known as the focus) and a fixed line (known as the directrix) is always constant. The equation of a parabola is a quadratic equation.
The equation of a parabola with a horizontal directrix is given by:
(x - h)² = 4p(y - k).
Where the directrix (y) = k - p, vertex = (h, k)
Given that: Vertex (1,0) and the Directrix y = -¼, Therefore:
vertex = (h, k) = (1, 0). h = 1 and k = 0.
y = k - p
but y = -1/4. Hence:
-1/4 = k - p
p = k + 1/4
p = 0 + 1/4
p = 1/4
Since the equation of the parabola is:
(x - h)² = 4p(y - k).
Substituting:
(x - 1)² = 4(1/4)(y - 0)
(x - 1)² = y
y = (x - 1)²
y = x² - 2x + 1
Solve the system by substitution.
y = 3x
y = -4x – 49
Answer:
Step-by-step explanation:
Substitute 3x into y=-4x-49
y=−4x−49
3x=−4x−49
3x+4x=−4x−49+4x(Add 4x to both sides)
7x/7=−49/7
(Divide both sides by 7)
x=−7
Step: Substitute−7forxiny=3x:
y=3x
y=(3)(−7)
y=−21(Simplify both sides of the equation)
Answer:
x=−7 and y=−21

Differentiate between a mathematical function, equation and expression? Function : 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 functionExpression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operatorsEquation : A mathematical equation is used to equate two expressions.Given are the system of equations as follows -
y = 3x
y = - 4x - 49
We have the equations as -
y = 3x .... Eq [1]
y = - 4x - 49 .... Eq [2]
Now, we can write the equation [2] as -
3x = - 4x - 49
7x = -49
x = - 7
So, we can find the value of [y] as -
y = 3x
y = 3 x - 7
y = - 21
Therefore, the solution set to the given system of equation is (- 7, - 21).

at a sale, dresses sold for 22.00 each. This price was 55% of a dress's original price.
Answer:
22.00x55%=12.10. 22-12.10=9.90
Answer:
$40
Step-by-step explanation:
22/55 = dollar per percent
dollar per percent = 0.4
0.4 x 100 will equal to 100% of the original price
0.4 x 100 = 40
to check, 40 x 55% = 22
