In this task, you will calculate the area of a complicated shape by splitting it into simpler shapes. Cut out shape C. Shape C is not a regular shape, so you cannot directly apply a formula to find its area. Split shape C into simpler shapes whose areas you can find by applying formulas. List the simple shapes into which you divided shape C, and measure their sides. Write all the measurements in inches.

Step-by-step explanation:

Perimeter is a measurement of the distance around a shape and area gives us an idea. Understanding how much space you have and learning how to fit shapes ... If the shape is a polygon, then you can add up all the lengths of the sides to find the perimeter. ... You can write “in2” for square inches and “ft2” for square feet

What is the sum of the interior angles of a regular polygon with 42 sides?

Answers

Answer:

Step-by-step explanation:

A regular polygon with 42 sides where the length of each side is 2 units. The units may either be inches or cm or km or miles: any unit of length.

You are given a Regular Polygon with 42 sides. What are the interior angles and exterior angles?

If the length of each side is 2 units, what is the perimeter, area, circum-radius and in-radius of the polygon?

n = 42

Perimeter of a polygon with 42 sides = (side length) x 42 = 84 units

Area of a polygon with 42 sides = (n x Side2 x cot (Π/n))/4 = (n x 22 x cot (Π/42))/4 = 560.45 square units

Sum of the interior angles of a polygon with 42 sides = (n-2) x 180 degrees = (42-2) x 180 degrees = 7200 degrees

Interior Angle of a polygon with 42 sides = (n-2) x 180/n degrees = (42-2) x 180/42 degrees = 171.42 degrees

Exterior angle of a polygon with 42 sides = 180 - Interior Angle = 180 - 171.42 = 8.57 degrees

Inradius = Radius of In-circle = (side length) x cot (Π/42) = 2 x cot 4 = 26.68 units

Circumradius = Radius of Circum-circle = (side length) x cosec (Π/42) = 2 x cosec 4 degrees = 26.76 units

Symmetry Group = D42 42 rotational symmetries and 42 reflection symmetries. The "D" stands for di-hedral.

The ratio of A ABC to ADEF is 6/5

HELP PLZZZZ!!!!

Answers

Answer:

x = 42

Step-by-step explanation:

Given that the ratio of ∆ABC to ∆DEF is 6/5, it means that:

AB/DE = BC/EF = AC/DF = 6/5

AB = x

DE = 35

Therefore,

AB/DE = 6/5

Plug in the values

x/35 = 6/5

Cross multiply

x*5 = 6*35

5x = 210

Divide both sides by 5

5x/5 = 210/5

x = 42

A mapping diagram shows a relation, using arrows, between inputs and outputs for the following ordered pairs: (negative 6, 0), (2, 1), (negative 7, negative 4), (11, 2), (3, 2). What is the domain of the relation? {x| x = –4 , 0, 1, 2}. {x| x = –7, –6, 2, 11, 3}. {y| y = –4, 0, 1, 2}. {y| y = –7, –6, 2, 11, 3}.

The domain is a set of input values so {x| x = –7, –6, 2, 11, 3} will be the domain of the relation therefore option (B) will be correct.

What is the range and domain of a function?

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

For example f(x) = x²

Now if we put x = 1 then it is called as domain variable while the value of function at x = 1 its that f(1) = 1 called range variable.

The domain is the set of all input values where the function is defined.

Since in the given relation ;

All input values have an output so all input values will be the domain of the given relation.

Hence "{x| x = –7, –6, 2, 11, 3} will be the domain of the relation".

PLEASE DO NOT COPY I SPENT THIS WHOLE DAY WORKING ON THIS< THIS IS JUST FOR FEEDBACK, so if anyone can give me feedback on my compare and contrast essay, then thank you. I was in shock when I heard from my social studies teacher that there are similarities between North and South Korea. All my life, I thought that the number of differences between the two countries would make it impossible for them to be alike in any other way. I even researched the countries and couldn't believe the number of similarities I found about them. I even found out that both countries used to be one country before the year 1948. it turns out that the government and economy of the north and south Korea are indeed different, but there are some similarities between the countries, such as culture when you think about it. Sometimes governments can separate countries from each other and bring countries to each other; an example of bringing the two countries together is that both south and north Korea gained independence on August 15, 1945, from japan. Simultaneously, examples of separating the two countries from each other are that North Korea's government is rigorous and almost controls everything, including investment, trade, visitors, internet, religion, traffic, and food/clothing. On the other hand, South Korea's government is not strict, and their economy is multiplying. When it comes to a country's government, nothing can change one country's relationship with another country, especially when the government breaks them apart. Occasionally, there are some differences in the economy between north and south Korea, but that never means that there will not be some similarities. For instance, north and south Korea are active in investing from other countries, and both countries have an electronics industry. Some diversity between the two countries is that the government entirely plans north Korea also only china and Russia are allowed to invest in North Korea on a tiny scale; another thing that differs them is that North Korea has industries that consist: electronics, telecommunications, chemicals, shipbuilding, and steel. While in the meantime, South Korea has sectors that consist: military products, machine building, electric power, textiles, tourism, and automobile production. South Korea also has a robust economy and is very famous for exports of cars, ships, computers, and other electronics. in conclusion, how many differences between the two countries' economies can never stop the similarities between them appear. When it comes to culture, North and South Korea have similarities but also have differences. For instance, both north and south Korea celebrate the same holidays/festivals; they have taekwondo as a popular traditional sport and the handbok, the Korean national costume. Yet in North Korea, citizens are taught to worship Kim sung while in South Korea; Confucius strongly influences citizens; Confucius is known as the first teacher in China who wanted to make education broadly available and instrumental in establishing the art of teaching vocation. He also set ethical, moral, and social standards that formed a way of life known as Confucianism. Even though there are some similarities, there can always be differences that come from a culture. There is no doubting that there arent any differences and similarities between north and south Korea's government, economy, and culture. Government shows you what and how something goes through in a country; the government also offers you many differences and a few similarities between the two countries. While the economy shows you what industries there are and what rank their country is in, it also shares some differences and similarities. On the other hand, culture explains what beliefs a country has and its traditions; culture also compares many things and contrasts a few things.
