Answer:
m<F = 79 degrees
Step-by-step explanation:
As per the given information;
m<E = 22, the triangle EDF (the one that is given in the picture) is isosceles (meaning that the sides are congruent).
In an isosceles triangle, (a triangle where the sides are congruent) the base angles (the angles opposite to the two congruent sides) are also congruent. One should also know, that in an isosceles triangle, like in any triangle, the sum of the measures of the angles equals 180 degrees.
Using this we can say that
m<D = m<F
To keep it simple while solving the problem, let's say that they have a value of x degrees.
So,
m<E + m<D + m<F =180
Subsitute
22 + x + x = 180
Simplify and inverse operations
22 + x + x = 180
-22 -22
2x = 158
/2 /2
x = 79
So the measure of <D and <F is 79 degrees.
Answer:
79
Step-by-step explanation:
An acute triangle adds up to 180
subtract 22 from 180
180-22 = 158
divide by 2
158/2 = 79

Find the value of x that makes each parallelogram the given type (answer both please)
Answers
Answer:
a. x = 12
b. x = 4
Step-by-step explanation:
a. RECTANGLE
ABCD is a rectangle, AC and BD are its diagonals.
Diagonals of a rectangle are congruent.
Therefore,
AC = BD
10x + 8 = 9x + 20
10x - 9x = 20 - 8
x = 12
b. RHOMBUS
Diagonal of a rectangle bisect opposite angles.
Therefore,
(5x + 3)° = (2x + 15)°
5x + 3 = 2x + 15
5x - 2x = 15 - 3
3x = 12
x = 12/3
x = 4
The value of x for a rectangle will be 12.
The value of X for a rhombus is 4.
What is a parallelogram?A basic quadrilateral containing two sets of side lengths is known as a parallelogram. There are four types of parallelograms each with diffrent kinds of properties.
a. RECTANGLE
ABCD is a rectangle, Therfore the diagonals that are made will also be equal.
AC = BD
[tex]10x +8 = 9x + 20\\10x - 9x = 20 - 8[/tex]
x = 12
b. RHOMBUS
As this is a rhombus that is presented, the angle which is divided with the help of the diagonal will both be equal.
5x + 3 = 2x + 15
5x - 2x = 15 - 3
Simplifying the equation,
3x = 12
x = 12/3
x = 4

The length of each side of an equilateral triangle is increased by 5 inches, so the perimeter is now 60 inches. Write and solve an equation to find the original length of each side of the equilateral triangle.
Answers
Answer:
The original length of each side of the equilateral triangle = x =15 inches
Step-by-step explanation:
Let Original length of side of equilateral triangle = x
If it is increased by 5 inches, the length will become = x+5
Since in equilateral triangle all the ides have same length so,
New Length of side 1 = x+5
New of side 2 = x+5
New Length of side 3 = x+5
Perimeter of triangle = 60 inches
We need to find the value of x
The formula used is: [tex]Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3[/tex]
Putting values in formula and finding x
[tex]Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3\\60=x+5+x+5+x+5\\60=3x+15\\60-15=3x\\45=3x\\x=\frac{45}{3}\\x=15[/tex]
So, the original length of each side of the equilateral triangle = x =15 inches

After translation:
Translation: (x, y) → (x-6, y-8)
W'X'Y'Z' = W'(-10, 0), X'(-10, -8), Y'(-18, -4), Z'(-14, 8)
After dilation:
Dilation: (x, y) → (2x, 2y), centered at (0, 0)
W''X''Y''Z'' = W'' (-20, 0), X'' (-8, 0) , Y'' (-24, 8), Z'' (-16, 32)
Step-by-step explanation:
Given the vertices of the Quadrilateral WXYZ
W(-4, 8)X(-4, 0)Y(-12, 4)Z(-8, 16)As the rule of translation is given by
Translation: (x, y) → (x-6, y-8)
So, after the translation the vertices of Quadrilateral WXYZ will be translated as:
W(-4, 8) → (x-6, y-8) ⇒ (-4-6, 8-8) = W'(-10, 0)
X(-4, 0) → (x-6, y-8) ⇒ (-4-6, 0-8) = X'(-10, -8)
Y(-12, 4) → (x-6, y-8) ⇒ (-12-6, 4-8) = Y'(-18, -4)
Z(-8, 16) → (x-6, y-8) ⇒ (-8-6, 16-8) = Z'(-14, 8)
Therefore,
W'X'Y'Z' = W'(-10, 0), X'(-10, -8), Y'(-18, -4), Z'(-14, 8)
Next, the rule of dilation is given by
Dilation: (x, y) → (2x, 2y), centered at (0, 0)
W'(-10, 0) → (2x, 2y) ⇒ (2(-10), 2(0)) = W'' (-20, 0)
X'(-4, 0) → (2x, 2y) ⇒ (2(-4), 2(0)) = X'' (-8, 0)
Y'(-12, 4) → (2x, 2y) ⇒ (2(-12), 2(4)) = Y'' (-24, 8)
Z'(-8, 16) → (2x, 2y) ⇒ (2(-8), 2(16)) = Z'' (-16, 32)
Therefore,
W''X''Y''Z'' = W'' (-20, 0), X'' (-8, 0) , Y'' (-24, 8), Z'' (-16, 32)

*HELP ME PLEASE* Consider the equation: 3x + 1 – 9 = 3(x + 2) + n.
Give a value of n so that the equation has no solutions.
Explain why you are correct.
Answers
Answer:
n = -14
Step-by-step explanation:
Let us try to solve this equation for n;
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 + n
3x - 3x -8 - 6 = n
-14 = n
The value of n = -14
This value is the value of the equation that will have no solution.
To know if we are correct, let us input this value into the expression
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 -14
Collect like terms;
3x - 3x = 8 + 6 - 14

increased.
Each year the percentage increase in value was the same each time.
The value of the house at the end of 2019 was 55.52% more than he paid for
the house.
Calculate the percentage increase in value of the house for each of the three
consecutive years.
Answers
The percentage increase in the value of the house each of the three years is 11.49%.
What is the percentage increase in the value of the house?The equation that can be used to represent the percentage change in the value of the house is:
(100x - 10%) + 3x% = 55.52%
90% + 3x = 55.52%
90% - 55.52% = 3x
34,48% = 3x
x = 34.48/3
x = 11.49%
