What are cosine formulas?In the cosine formulas, the cosine (cos) function is discussed. Consider a right-angled triangle with one acute angle, x. The cosine formula is cosx = (adjacent side) / (hypotenuse), where "adjacent side" refers to the side adjacent to angle x and "hypotenuse" refers to the longest side of the triangle.
As per cosine rule fore given [tex]$\triangle$[/tex]ABC:
[tex]$\cos \theta=\frac{b^2+c^2-a^2}{2 b c}$$$[/tex]
According to the question;
For a given [tex]$\triangle$[/tex]ABC;
cos e < 0.
Therefore, [tex]\quad \frac{b^2+c^2-a^2}{2 b c} < 0 \\[/tex]

Find x and the measure of each side.
Δ M N P is isosceles with MN ≅ NP. MN is two less than five times x, N P is seven more than two times x , and P M is two more than three times x .
The value of x is 3 and the measure of each side of isosceles ΔMNP is:
MN = 13
NP = 13
PM = 11
We know that, in an isosceles triangle, any two sides of the triangle are equal and the angle opposite to these sides are equal in measure.
In this question, we have been given an isosceles ΔMNP with MN ≅ NP .
Also we have been given some statements about the sides of isosceles ΔMNP.
MN is two less than five times x.
We write above statement as mathematical expression.
MN = 5x - 2
NP is seven more than two times x.
We write above statement as mathematical expression.
NP = 7 + 2x
And PM is two more than three times x.
We write above statement as mathematical expression.
PM = 2 + 3x
As MN = NP
⇒ 5x - 2 = 7 + 2x
⇒ 5x - 2x = 7 + 2
⇒ 3x = 9
⇒ x = 3
So, the value of x is 3.
Now we find the measure of each side of triangle JKL
MN = 5x - 2
MN = 5(3) - 2
MN = 15 - 2
MN = 13
Now the side NP
NP = 7 + 2x
NP = 7 + 2(3)
NP = 13
And side PM would be,
PM = 2 + 3x
PM = 2 + 3(3)
PM = 11
Therefore, the value of x is 3 and the measure of each side of isosceles ΔMNP is:
MN = 13
NP = 13
PM = 11

Draw a line segment with endpoints M and R. Now draw a parallel line segment that is the same length as MR¯¯¯¯¯¯¯¯¯ with the endpoints M′ and R′ in the same order.
Which answer correctly describes the transformation from MR¯¯¯¯¯¯¯¯¯ to M′R′¯¯¯¯¯¯¯¯¯¯¯¯?
The required transformation would be in the variable because the slope of parallel lines is always the same.
A line can be defined by the shortest distance between two points is called as a line.
Here,
Line MR is drawn with the endpoints M and R, and another line M'R' is drawn which is parallel to line MR. There is a property of parallel lines that the slope of the parallel lines is always equal. , So the slope of lines are equal there must be a change in variable x and y which describes the translation of the line M'R'.
Thus, the required transformation would be in the variable because the slope of parallel lines is always the same.

If a/b = c/d then a and d are the extremes.
Ratio is defined as the comparison of two quantities. The ratio between quantities a and b can be expressed as a : b or a/b.
example:
There are 3 girls for every 5 boys in a class. Then, the ratio of girls to boys is 3 : 5 or 3/5.
On the other hand, proportion is defined as the equality between two or more ratios.
a : b = c : d
Two ratios are equivalent if their cross-products are equal. Cross products are the products of the extremes and means. The 1st and and 4th terms of a proportion is called the extremes, while the 2nd and 3rd is the means of a proportion.

1 A map has a scale factor of 1 : 24 000
The distance between two towns is 3.6 km.
How far will this be on the map?
The two towns will be 15 centimeters apart on the map.
Here, we are given that a map has a scale factor of 1:24 000.
This means that if the distance between two points on the map is say 1 meter then in reality, these two points will be 24,000 meters apart.
Now, we are given that two towns are 3.6 kilometers apart
That is in reality, they are 3.6 km away
Let them be x kilometers away on the map
The ratio of the distances on map and in real life must be equal to 1/24,000
⇒ x/3.6 = 1/24,000
x = 3.6/24,000
x = 0.00015 kilometers

If the labor force of 165 million people is growing by 1.2 percent this year, how many new jobs have to be created each month to keep unemployment from increasing?
0.165 million jobs must be created monthly to keep unemployment from increasing.
What is the labor force?The combined employed and unemployed population makes up the labor force. The labor force as a percentage of the civilian noninstitutional population is the labor force participation rate.The number of employed persons plus the number of jobless people seeking work is known as the labor force. 1 The unemployed who are not looking for work are not included in the labor pool. For instance, stay-at-home mothers, retirees, and students are not employed.An economy's labor force is calculated as the sum of employed and jobless citizens. As a result, the labor force can be calculated using the formula: labor force = employed population + unemployed population.All employees are included in the labor force, including persons looking for work who are unemployed and the companies who pay their workers. A job seeker would not be regarded as an employee even if she were included in the labor force.How many new jobs have to be created each month to keep unemployment from increasing?
The population of the labor force = is 165 million
Percentage increase of labor force in a year = 1.2 % of 165 million
Percentage increase in the labor force in a month 1.2 %/12=0.1 %= of 155 million
Jobs required to be created each month = population increase each month
165 million *0.1/100=0.165 million

In this question,
Paige is choosing between 10 books at the library.
We need to find the probability that she chooses 3 particular books to check out from the 10 initial books.
The probability of choosing 1 book = 1/10
So, the probability of success (p) = 1/10
the probability of failure (q) = 9/10
Using Binomial probability distribution,
P(x = 3) = [tex]^{10}C_3\times (\frac{1}{10} )^3\times (\frac{9}{10} )^7[/tex]
