Which angle is congruent to angle 3 and explain why
I will give a brainless for a correct answer :)
Answer:
Angle 6
Step-by-step explanation:
One easy way to know if an angle is congruent is it being directly across from the angle. In this case its fairly easy to tell since (assuming) that angle 3 is a 90 degree angle and so is angle 6.

What is the value of x in the equation *x - y = 30, when y = 15?
4.

Answer:
45
Step-by-step explanation:
[tex]x[/tex] - [tex]y[/tex] = 30 and [tex]y[/tex] = 15
So, I guess you are just messed up with the Xs and Ys.
And I'm not sure what is the 4. ООО 8 80 200 about but here is my guess :
So [tex]x[/tex] - [tex]y[/tex] = 30 and [tex]y[/tex] = 15.
First step, substitute the [tex]y[/tex] into the equation [tex]x[/tex] - .
So, it would be
[tex]x[/tex] - 15 = 30.
Now, we need the value of [tex]x[/tex].
[tex]x[/tex] - 15 = 30
Group the terms together :
[tex]x[/tex] - 15 ( +15 ) = 30 ( +15 )
So, [tex]x[/tex] would be equals to 30 + 15. And in other words, it would be 45.
So :
[tex]x[/tex] = 45.
Wanna check whether my answer's correct?
Substitute [tex]x[/tex] into [tex]x[/tex] - 15 = 30
That would be :
45 - 15 = 30
So is 45 - 15 = 30?
Yep.
So 45 is the answer.
The value of X is 45.

What is 2 + 2i in polar form?
The polar form of 2+2i is [tex]$2\sqrt{2}(\cos(\frac{\pi}{4}) + i\sin(\frac{\pi}{4}))$[/tex]
We are given that;
The complex number= 2+2i
Now,
To convert a complex number from rectangular form to polar form, we need to find its magnitude and argument.
The magnitude is the distance from the origin to the point (x, y) on the complex plane, and the argument is the angle between the positive x-axis and the line joining the origin and the point.
Using the Pythagorean theorem and the inverse tangent function, we get:
Magnitude = [tex]$\sqrt{x^2 + y^2}$[/tex]
Argument = [tex]$\tan^{-1}(\frac{y}{x})$[/tex]
Plugging in x = 2 and y = 2i, we get:
Magnitude = [tex]$\sqrt{2^2 + 2^2} = \sqrt{8} = 2\sqrt{2}$[/tex]
Argument = [tex]$\tan^{-1}(\frac{2}{2}) = \frac{\pi}{4}$[/tex]
Therefore, by pythagoras theorem answer will be [tex]$2\sqrt{2}(\cos(\frac{\pi}{4}) + i\sin(\frac{\pi}{4}))$[/tex].

How is the distributive property used to expand expressions? For example if the equation was: 2(x + 3)=30
Step-by-step explanation:
So how is the distributive property used to expand expressions? Let's use your example.
We have 2(x + 3) = 30
It seems like we're stuck, we cannot add a variable by a real number, can we? This is when the distributive property comes into play, we will use the 2 outside of the parenthesis to multiply x and 3.
2(x) + 2(6) = 30
We multiply the number inside the parenthesis since we can't solve the inside of it, therefore causing it to expand.
4(x + 5) = 43
4(x) + 4(5) = 43

What is the exact value of sin 170⁰ cos 55⁰ + cos 170⁰ sin 55⁰?
The value of the equation sin 170° cos 55° + cos 170° sin 55° is given by
C = sin 225° and the value of C = -0.70710678118
What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the equation be represented as C
Now , the value of A is given by the equation ,
A = sin 170° cos 55° + cos 170° sin 55°
And let the first angle be = 170°
Let the second angle be = 55°
So , value of A = 170° and value of B = 55°
From the trigonometric relations , we know that
sin ( A + B ) = sin A cos B + cos A sin B be equation (1)
Substitute the values of A and B in the equation , we get
sin 170° cos 55° + cos 170° sin 55° = sin ( 170° + 55° )
So , value of equation A = sin ( 170° + 55° )
On simplifying the equation , we get
sin ( 170° + 55° ) = sin 225°
The value of sin 225° = -0.70710678118
Hence , The value of the equation sin 170° cos 55° + cos 170° sin 55° is given by C = sin 225° and the value of C = -0.70710678118

Winter is coming, so Sasha decides to buy new outdoor gear. She has a coupon good for 25% off. She buys a coat with an original price of $85.75, a pair of boots with an original price of $71.99, a scarf with an original price of $24.25, and a pair of gloves with an original price of $44.95. She pays a total of $208.94. To which item did Sasha apply her coupon? a. coat b. boots c. scarf d. gloves
Yes, the answer is B. Boots
Edgenuit.y 2021
On boots Sasha applied the coupon of 25%, option B is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
If Sasha paid a total of $208.94 and applied the 25% coupon to one of the items, then we can set up the following equation:
$85.75 + $71.99 + $24.25 + $44.95 - 0.25x = $208.94
where x is the original price of the item to which Sasha applied the coupon.
Simplifying the equation, we get:
$226.94 - 0.25x = $208.94
0.25x = $18.00
x = $72.00
This means that the original price of the boots was $71.99, and Sasha applied the 25% coupon to the boots, getting a discounted price of:
$71.99 - 0.25($71.99) = $53.99
Therefore, On boots Sasha applied the coupon of 25%, option B is correct.

If there are 5 levels of Factor A and 7 levels of Factor B for an ANOVA with interaction, what are the interaction degrees of freedom?
a. 24.
b. 12.
c. 10.
d. 35.
Answer:
C. 10Step-by-step explanation:
let n1 be the degree of freedom of factor A
Let n2 be the degree of freedom of factor B
If there are 5 levels of factor A, then n1 = 5
If there are 7 levels of Factor B then n2 = 7
The interaction between the degrees of freedom is expressed using the formula;
df = (n1 - 1)+(n2 - 1)
df = n1 -1 + n2- 1
df = n1+n2 -2
Substitute n1 and n2 and get df
df = 5+7-2
df = 12-2
df = 10
Hence the interaction degree of freedom is 10

Which of the following best describes DG?
E
G. F
D
A. Perpendicular bisector
B. Altitude
C. Angle bisector
D. Median
Answer:
I think its option D. MEDIAN
The segment DG in the given triangle describes as Altitude.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
Given that,
A triangle DEF.
Now, Altitude of a triangle is defined as the perpendicular segment drawn from a vertex to the opposite side.
Angle bisector is the line segment drawn from a vertex to the opposite side which bisects the angle at that vertex.
Perpendicular bisector is the perpendicular line segment drawn from a vertex to the opposite side which divides the opposite side to two halves.
Median is the line segment joining the vertex with the mid point of the other side.
Here, it is only given that the drawn line is perpendicular. It does not bisect side or angles.
So it is altitude.
Hence the given segment is altitude.
