Answer:
b = 76°
Step-by-step explanation:
Hi there,
It is important to know that the sum of all the angles in any triangle equals 180°.
For this problem, we can write the following equation:
32° + 72° + b° = 180°
104° + b° = 180°
b° = 76°
Hope my explanation helps. Cheers.
The equation y=21.2x represents Austin's earnings in dollars and cents, y,
for working x hours. Find the rate of change.
Given:
The equation is
[tex]y=21.2x[/tex]
Where, y is earnings for working in dollars and cents and x is the number of working hours.
To find:
The rate of change.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y=21.2x[/tex] ...(ii)
On comparing (i) and (ii), we get

Answer:
∠10 + 12(3) = 46°
∠15(3) + 1 = 46°
Step-by-step explanation:
the angles are equal because they are corresponding angles
(10+12x) = (15x+1)
reduce:
3x = 9
x = 3
10 + 12(3) = 46°
15(3) + 1 = 46°

recall that the inside angles of a triangle add up to 180
Step-by-step explanation:
now add up all the angles and make it equal to 180 :)
as follows
X+58+45+85 = 180
now use algebra ... and solve for X :)
X = 180-58-45-85
my calculators tells me....
X = -8
what does that answer mean?
it's saying ... like this 58-8 is that angle.. does that help ? :)

Find the coordinates of the image's vertices.
6. A triangle with vertices ((-2,4), M(-2, 8), and N(-6, 4) is rotated 90° counterclockwise about the origin.
a. L'(-2,-4), M'(-2, -8), and N'(-6,-4)
b. LT-4,2), M (-8,2), and NY-4, 6)
c. L'44,-2), M'(-8,-2), and N'Y 4, 6)
d. L(4-2), M'(8,-2), and N (4-6)
The coordinates of the triangle after the rotation is L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )
What is Rotation?The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (-y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)
Given data ,
Let the triangle be represented as ΔLMN
L ( -2 ,4 ) , M ( -2 , 8 ) , and N ( -6 , 4 )
Now , the rotation angle is = 90° counterclockwise about the origin
Let the coordinates of the rotated triangle be ΔL'M'N'
where , 90° counterclockwise rotation: (x,y) becomes (-y,x)
So , L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )
Hence , the rotated triangle is L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )

I need help with this
Answer:
-20xy + 4xz + 48x
Step-by-step explanation:
Just Distribute :)
Answer:
48x-20xy+4xz
Step-by-step explanation:
You need to distribute the 4x to the rest of the equation so the equation will become 48x-20xy+4xz, this is because 4x * 12 = 48x and 4x*-5y =-20xy and it's xy because x comes before y in the alphabet and then lastly 4x * z same thing it's gunna be xz, so the answer is 48x-20xy+4xz.

Answer:
x = 2
Step-by-step explanation:
We'll start with this useful fact about triangles: equal angles in a triangle sweep out equal sides. If a 45 degree angle here sweeps out a length of x, the other one must do the same, so the legs of this right triangle must both be x.
Next, we can use the Pythagorean Theorem to tie all of the triangle's lenghts together:
x² + x² = (√8)²
Finally, we can solve for x:
2x² = 8
x² = 4
x = 2.

Since this is Equilateral Equiangular triangle each angle is going to be 60 degrees (sum of the interior angles of a triangle is 60 degrees).
Answer: y = 8
Step-by-step explanation:
Firstly, to solve this problem, we must identify what type of triangle this is.
This is an equalateral/equiangular triangle. This means that the sides are the same size and most importantly, the angles are the same degrees. How do we know this though? We know this because if a triangle is equilateral, it has equal angles. The reason we know this is an equilateral triangle is that it is denoted by the marks of congruency or the little dashes on the sides. All triangles that are equiangular have the same three angles of 60 degrees each. To top that off, 60 x 3 = 180, the number of degrees a triangle must have together for it to be considered a triangle. So how do we figure this out though?
Firstly, we must make the equation EQUAL to 60 degrees
60 = 8y - 4
Then simply solve
Add the 4 to each side, we need to do the reverse sign to get rid of it on the variable side. So it would be positive (+4)
60 + 4 = 8y
64 = 8y
Then, simply, we divide each side by 8 to get our answer!
64/8 = 8y/8
8 = y
y = 8
You can confirm by plugging the 8 into y, and you will get 60.

Solve with elimination
Answer:
5
Step-by-step explanation:
{
3x−y=2
2x−y=3
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
3x−y=2,2x−y=3
Subtract 2x−y=3 from 3x−y=2 by subtracting like terms on each side of the equal sign.
3x−2x−y+y=2−3
Add −y to y. Terms −y and y cancel out, leaving an equation with only one variable that can be solved.
3x−2x=2−3
Add 3x to −2x.
x=2−3
Add 2 to −3.
x=−1
Substitute −1 for x in 2x−y=3. Because the resulting equation contains only one variable, you can solve for y directly.
2(−1)−y=3
Multiply 2 times −1.
−2−y=3
Add 2 to both sides of the equation.
−y=5
Divide both sides by −1.
y=−5
The system is now solved.
x=−1,y=−5
