The ratio of the measures of the three angles in a triangle is 2:9:4. Find the measures of the angles. ​

Answers

Answer 1

Answer:

Let the three angles be 2x,9x & 4x

By the problem,2x+9x+4x=180

15x=180

x=180/15

x=12

there fore the angles are

2x= 2*12=24°

9x=108°

4x=48°

find the value of x and please show how

Answers

Answer:

x = 12°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

So,

39° + 53° + 4° + 7x = 180°

Add all the numbers on the left up.

96° + 7x = 180°

Subtract 96 from both sides.

7x = 84°

x = 12°

Hope this helps!

Answer: x= 12

Step-by-step explanation:

Triangle angle sum theorem says that the interior angles of a triangle sum to 180 degrees. Set the sum of all of these angles equal to 180 to solve. 39+53+ (4+7x) = 180. Combine like terms. 96 +7x = 180. Subtract 96 from both sides. 7x = 84. Divide both sides by 7. X = 12

PLEASE HELP QUICKLY!!

Answers

Answer:

79

Step-by-step explanation:

Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.

m4 = 79 because 180 - 101 = 79

The missing side lengths of the right triangles are AC = 13 and DE = 24.

What is the Pythagorean theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given the two right triangles.

The hypotenuse of the first right triangle is given by:
AC² = 5² + 12²

AC² = 25 + 144

AC² = 169

AC = 13

The length of the leg in the second triangle is given by:

DE² = 26² - 10²

DE² = 676 - 100

DE² = 576

DE = 24

Hence, the missing side lengths of the right triangles are AC = 13 and

DE = 24.

constant of direct variation. -12 + 8y +12 = 7x.

Answers

Given:

The equation is

[tex]-12+8y+12=7x[/tex]

To find:

The constant of direct variation if the given equation represents direct variation.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]            ...(i)

Where, k is the constant of proportionality.

We have,

[tex]-12+8y+12=7x[/tex]

[tex]8y=7x[/tex]

[tex]y=\dfrac{7}{8}x[/tex]          ...(ii)

At x=0,

[tex]y=\dfrac{7}{8}(0)[/tex]

[tex]y=0[/tex]

The equation (ii) passes through (0,0). So, it represents a proportional relationship.

On comparing (i) and (ii), we get

[tex]k=\dfrac{7}{8}[/tex]

Therefore, the constant of proportionality is [tex]k=\dfrac{7}{8}[/tex].

I wrote it and if you have any pointers on how to make is better :)??? i am writing a speech it for a couple of composers is specifically classical music and I need some advice hahaClassical Music is the type of music that is very serious or conventional, which follows long-established principles different from jazz. I believe it is very important for almost everyone, as it helps people feel relaxed and rejuvenate their spirits. It helps in experiencing a huge gradual range of emotions, such as despair, love, happiness, and even sadness. This specific type of music is important as it serves various purposes; it helps people in getting away from all the confusion in life and focus on lifes goals, such as a job opportunity, or just an accomplishment.This fascinating type of music helps put me into a zone to just completely focus on whatever subject I need to. I believe Classical Music is something most people find beautiful, and I think others may not even understand. My thoughts to do this speech immediately went to classical music and how I find it not just beautiful, but emotionally sole-shatteringly sometimes. Classical music, I believe, has the power of moving someone emotionally without speaking a word, it isn't just noises thrown together, it's something that a person has learned to create so carefully. Each note is put together to make the perfect piece. It can feature one instrument or multiple and can be replicated so that it's never lost.There is a world-renowned composer, which I am sure all of you know. His name is Ludwig van Beethoven. Beethoven was a German composer and pianist, born December 1770, Bonn, Germany. Beethoven was a German composer and pianist. Beethoven remains one of the most admired composers in the history of Western classical music. His works span the transition from the classical period to the romantic era in classical music. They are famous for their great strength to empower you in his pieces of music. My most personal favorite is Beethoven Moonlight Sonata - Piano Sonata No. 14, this piece was designed to let you focus. Beethoven music you can listen to for hours, they are absolutely fascinating to hear and almost feel how wonderful it is.Classical music expresses the deepest thoughts of our civilization. Composers paint an image of the society and times within which they lived. you'll be able to expertise the greatness and achievements of another generation through its music.

Music continues to bridge the nice divide between cultures and countries. It will bring hope for peace within the darkest of times.Classical music has its own noble history just like the remainder of the music types. each culture and tradition has its own type of classical music that competes with the help of various instruments for instance Indians, Chinese, Arabs, and Europeans had their own traditions for classical music. The genre may be a broad, somewhat inexact term, pertaining to music produced, or frozen within the traditions of art, religion, and concert music. Music is classical if it includes a number of the subsequent features: a learned tradition, support from the church or government, or larger cultural capital. genre is additionally delineated as complex, lasting, transcendent, and abstract.Thank you. can someone pls help its rate of change and i only need to do all of the evens. its due in an hour What are two reasons that Mao thought young people were importantto Chinas future?
