EG = EF + FG = 6.1 + 6.1 = 12.2
if each quadrilateral below is a square,find the missing measures
Answers
Answer:
∆EFG = 90°
∆GDH = 45°
∆FEG = 45°
∆DHG = 90°
The measure of the given angles are -
m ∠EFG = 90°
m ∠EFG = 45°
m ∠FEG = 45°
m ∠DHG = 45°
What is square?A square is a quadrilateral with all sides congruent to one another.
Given is to find the measure of angles given in the question.
We can write the measure of angles as -
m ∠EFG = 90°
m ∠EFG = 45°
m ∠FEG = 45°
m ∠DHG = 45°
Therefore, the measure of the given angles are -
m ∠EFG = 90°
m ∠EFG = 45°
m ∠FEG = 45°
m ∠DHG = 45°

Gabriel purchases a rug priced at $475. With sales tax, the total comes out to $513. What is the sales tax percentage?
Answers
Answer:
The tax is 8%
Step-by-step explanation:
Take the final price and subtract the original price
513-475 = 38
Divide by the original price
38/475 =.08
Change to percent form
8%
The tax is 8%
513 - 475 = 38
38/475 = 0.08
To check your work.
475 x 0.08 = 38
475 + 38 = 513
Meaning the answer is 8%

Question:
Is triangle AFD congruent to triangle BEC?
Answers
Answer: is not congruent
To be congruent, it has to be same size and shape. It can face in any directions. Both the shapes have to be equal in all side lengths and equal angles.
Looking at the triangle you can understand that it is not congruent as the triangles have a size difference of being big and small. But if you still desire detailed explanation then here:
There is four rules for a triangle to be congruent. If one of these rule matches then you can say the triangle is congruent.
1. The three sides are equal
2. Two angles are the same and a corresponding side is the same
3. Two sides are equal and the angle between the two sides is equal
4. Two angles are equal and the side between them is equal
There are no angles, so find if all the three sides are equal. Even if one side is not equal, you can say it is not congruent. So if you just measure any side length of the smaller and big triangle, the length is not equal. None of the side lengths in either of the triangle is equal.

2. Graph attached below:
Step-by-step explanation:
1) To find to slope of the line with two points would be the following equation:
[tex]y_{2} - y_{1} / x_{2} - x_{1}[/tex]
So let’s assume our variables and subsitute them to see that the Carma’s Working out is an error.
Form: [tex](x_{2}, y_{2}), (x_{1}, y_{1})[/tex]
[tex]y_{2} = 3[/tex]
[tex]y_{1} = 1[/tex]
[tex]x_{2} = 7[/tex]
[tex]x_{1} = 11[/tex]
[tex]3 - 1 / 7 - 11 = -1/2[/tex]
1. Error one: The point values of the slope aren‘t correctly labeled and are not the same form as in the formula.
2. Error two: The slope output is not correct, it is 2 but the slope is -1/2.
Now let’s get on the graph of Carma’s workout, I can spot that the point (-4, 5) is not plotted correctly. Instead it is plotted (4, -5). To understand clearly I will label these points on a graph, image attached below:
3. Error three: The point (-4, 5) is not plotted correctly, x should be negative and y should be positive.
4. Error four: The slope is not correct, instead the slope of the graph is negative but we need a positive slope.
Now it is time to fix Carma’s mistakes:
1) Slope: -1/2
2) Graph attached below

Find the value of c that makes the trinomial a perfect square: x^2– 40x + c
Answers
Answer:
c=400
Step-by-step explanation:
Use the perfect square formula:
ax^2+bx+c=0
x^2-40x+c=0
bring c to the other side
x^2-40x+___=-c
divide -40 by 2 then square it; 400
add 400 to each side
c=400
(x-20)(x-20)
The value of c that makes the trinomial a perfect square x²– 40x + c is 400.
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
We have to find the value of c that makes the trinomial a perfect square: x²– 40x + c
Lets use the perfect square formula:
ax²+bx+c=0
The given equation is given below.
x²-40x+c=0
Take the c term to the right hand side
x²-40x=-c
x²-40x+400=-c+400
c=400
Hence, the value of c that makes the trinomial a perfect square x²– 40x + c is 400.
