What is n and m? In the angle
In the given triangle , ∠n = 50° and ∠m = 35°
What is an angle ?In the geometry, angle is defined as the geometry formed by the multiple rays. Or we can also say that the angle is a figure formed by two rays with having same initial point. The rays are also known as the sides of the angle. A angle can have two rays.
Some common terms related to angles :
Endpoint : It is the point where the rays met to each other.Ray : Ray is the side or line segment on which angle is formed.Curve : It is a line but not straight i.e. a bended line.Tangent : A line which touches the surface of curve.In the given question mark the triangle as ABC and the mid line as point D.
that means,
∠A = ∠n
∠B = ∠m
and, in ΔABC
∠C = 60 + 35 =95
now, as ΔCDB is isosceles triangle therefore,
∠m = ∠C = 35°
Also, as sum of all angle of triangle is 180
Therefore, ∠A + ∠B + ∠C = 180
=> ∠n + ∠m + 95 = 180
=> ∠n + 35 + 95 = 180
=> ∠n = 180- 130
=>∠n = 50
Hence in the triangle given , ∠n = 50 and ∠m = 35

C (7,-4) and D = (-8,-5)
CD= [?]
HINT: Use the distance formula:
d = √(x₂-x₁)² + (y2-Y₁)²
Round your answer to the tenths place.
The distance between two points [tex](x_{1}, y_{1} )[/tex] and [tex](x_{2} ,y_{2})[/tex] is given by
[tex]d = \sqrt{ (x_{2} -x_{1})^{2} +(y_{2} -y_{1})^{2} }[/tex] …(1)
Given points are:
C = (7,-4) = [tex](x_{1}, y_{1} )[/tex]
D = (-8,-5) = [tex](x_{2} ,y_{2})[/tex]
Substituting the values in equation (1), we get
[tex]CD = \sqrt{ (-8-7)^{2} +(-5-(-4))^{2} }[/tex]
[tex]CD = \sqrt{ (-15)^{2} +(-1)^{2} }[/tex]
[tex]CD = \sqrt{{ 225} +1 }[/tex]
[tex]CD = \sqrt{{ 226 }[/tex]
[tex]CD = 15.03}[/tex]
After Rounding it to nearest tenth, we get
CD = 15 units
Hence, the distance between the points (7,-4) and (-8,-5) is 15 units.

The length of a rectangle is 3 more than twice the width. the perimeter is 36 inches. what is the area?
If the length of a rectangle is 3 more than twice the width and the perimeter is 36 inches, then the area of the rectangle is equal to 65 in².
The length and width of the rectangle can be determined by using the formula for the perimeter of the rectangle,
P = ( L + W ) × 2
P = 2L + 2W
Here L is equal to the length of the rectangle and W is the width of the rectangle.
As the length is 3 more than twice the width, we can write the length of the rectangle as,
L = 3 + 2W
Putting L = 3 + 2W in the equation of perimeter,
P = 2L + 2W
As P = 36
36 = 2( 3 + 2W) + 2W
36 = 6 + 4W + 2W
6W = 30
W = 30 ÷ 6
W = 5
The length of the rectangle can be found by putting W = 5 in the equation,
L = 3 + 2W
L = 3 + 2(5)
L= 3 + 10
L = 13
Therefore, the length and width of the rectangle are equal to 13 and 5 respectively
As, area = width × length
area = 5 × 13
area = 65
Hence, the area of the rectangle is equal to 65 square inches.

Answer: 49 & 82
Step-by-step explanation:
*the total degrees for each triangle is 180 degrees
9) Start with the triangle furthest left- subtract 71 and 57 both from 180. That leaves you with 52 degrees for that third angle. The angles that all make a straight line or straight angle add up to 180 degrees as well. Now, subtract the 52 and 65 from 180, which leaves you with 63 degrees for the first angle in the second triangle. Now subtract the 63 and 68 from 180, which leaves you with 49 degrees for that answer.
10) For this one, you will start with the triangle further right, since it already has two angles shown. Subtract the 85 and 35 from 180, which gives you 60 degrees for that third angle. Then, you can use the vertical angles to fill in its opposite angle in the first triangle (vertical angles are equal). This means that the first triangle has angles of 38 and 60 degrees, so subtract those both from 180, giving you 82 degrees for that answer.

Yesterday, between noon and midnight, the temperature dropped by 28.4°F. If the temperature was -1.9°F at midnight, what was it at noon?
Answer:
n= 26.5
Step-by-step explanation:
Comment
You need some sort of formula for this question. But you more or less have to invent it.
Formula
Temperature midnight = noon - temperature drop
Givens
temperature drop = 28.4
temperature midnight = -1.9
Temperature noon = x
Solution
-1.9 = x - 28.4 Add 28.4 to both sides
-1.9 + 28.4 = x-28.4+28.4 Combine
Answer
26.5 = x

The measure of angle JKN is 108 degrees
How to determine the measure of angle JKN?From the figure, we have the following parameters
Angle 1 equals Angle 2
Where
Angle 1 = Angle JKP = 3r + 12
Angle 2 = Angle PKN = 4r - 2
Recall that
Angle 1 equals Angle 2
So, we have
3r + 12 = 4r - 2
Evaluate the like terms
r = 14
Substitute r = 14 in Angle 1 = Angle JKP = 3r + 12 and Angle 2 = Angle PKN = 4r - 2
Angle 1 = Angle JKP = 3 * 14 + 12 = 54
Angle 2 = Angle PKN = 4 * 14 - 2 = 54
The measure of angle JKN is calculated as
Angle JKN = Angle 1 + Angle 2
So, we have
Angle JKN = 54 + 54
Evaluate
Angle JKN = 108
Hence, the measure of angle JKN is 108 degrees

The linear equation y= mx + b contains the point (-4, 3) and is perpendicular to the line 5x + 20y = 9. What is the value of m? What is the value of b?
The value of m and b of the linear equation are 4 and 19 respectively
How to represent linear equation?The linear equation is represented as y = mx + b, contains the point (-4, 3) and is perpendicular to the line 5x + 20y = 9
Linear equation can be represented as follows:
In slope intercept form,
y = mx + b
where
m = slope or gradientb = y-interceptTherefore, the linear equation y = mx + b contains the point (-4, 3) and is perpendicular to the line 5x + 20y = 9.
Perpendicular lines follows the following rules:
m₁ m₂ = -1
Therefore, let's find the slope of the second equation and use it to find the slope of the linear equation that passes through (-4, 3).
5x + 20y = 9
20y = -5x + 9
y = -1 / 4 x + 9 / 20
Hence,
- 1 / 4 m₂ = - 1
m₂ = 4
Therefore, let's find the equation since we have gotten the slope.
y = 4x + b
It's passing through (-4, 3)
3 = 4(-4) + b
3 = -16 + b
b = 3 + 16
b = 19
Therefore, the value of m and b of the linear equation are 4 and 19 respectively

Anika spent $38 on 9.5 gallons of fruit punch. What is the cost per gallon? p= w= %=
The required cost of the punch is $4 per gallon.
Given that,
Anika spent $38 on 9.5 gallons of fruit punch.
To determine what is the cost per gallon.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Total volume purchased = 9.5 gallons
Total cost = $38
Now,
The ratio of the total cost of punch to the volume of fruit punch purchases the total cost will give as the cost per gallon. So,
cost per gallon = 38 / 9.5
= $4 per gallon
Thus, the required cost of the punch is $4 per gallon.

Three arithmetic means between 12 and 44
The three arithmetic means between 12 and 44 are -
20, 26, 36.
We have two numbers 12 and 44.
We have to determine the three arithmetic mean between these numbers.
What is Arithmetic Mean ?Assume that x, y and z are in AP, then -
y - x = z - y
2y = x + z
y = (x + z)/2
Here - y is called the arithmetic mean of x and z.
According to the question -
Assume that the three arithmetic means between the two numbers are -
12, a, b, c, 44
Then -
12 , 12 + d, 12 + 2d, 12 + 3d, 44
will be an AP with common difference 'd'.
Now, we have -
a[5] = 44
Using the formula for nth term of an AP, we get -
a + (n - 1)d = 44
12 + 4d = 44
4d = 32
d = 8
Therefore, the three arithmetic means are -
12 + 8 = 20
12 + 2 x 8 = 26
12 + 3 x 8 = 36
Hence, the three arithmetic means between 12 and 44 are -
20, 26, 36

0.5(7d+4)=7−1.5d ..............................
Answer:
d=1
Step-by-step explanation:
First let's simplify the first equation, 0.5(7d+4) by applying the distributive property
0.5(7d+4)
(0.5 x 7d) + (0.5 x 4)
3.5d+2
Now let's move all terms containing d to the left side of the equation
So add 1.5d to the left
3.5d+2 = 7-1.5d
3.5d+2+1.5d=7
5d+2=7
Move all terms not containing d to the right side of the equation
5d+2=7
5d=7 -2
5d=5
Finally, divide each term by 5 to simplify
5d/5 = 5/5
d=1
