The measure of angles in a triangle are in a ratio of 2:3:4. What are the measures of the angles?

Answers

Answer:

The angle measures are 40°, 60°, and 80°.

Step-by-step explanation:

When we are given this problem, we need to know that

There are three angles in a triangle.These angles add up to equal 180°.

With this ratio, these angles must add up to equal 180°. Therefore, we can set up an equation and add an x-variable to each of the numbers. We then set this equal to 180.

[tex]\text{2x + 3x + 4x = 180}\\\\\text{9x = 180}\\\\\text{x = 20}[/tex]

Now, we need to find the measures of the angles. The angles are the parts of the ratio multiplied by the value of x.

[tex]\text{2(20) = 40}\\\\\text{3(20) = 60}\\\\\text{4(20) = 80}[/tex]

So, our three angles measures should be 40°, 60°, and 80°. We can check this by adding up these three values and seeing if the sum equals 180°.

[tex]\text{40 + 60 + 80 = 180}\\\\\text{100 + 80 = 180}\\\\\text{180 = 180}[/tex]

Because this is true, our angle measures are 40°, 60°, and 80°.

Find the equation of the line that contains the points (-5, 0) and (-3, 4)

Answers

Answer:

y = -1/2x - 5/2

Step-by-step explanation:

With points (-5,0) and (-3,4), we need to find the slope first.

[Find slope of points]

Using slope formula m = (Y2 - Y1) / (X2 - X1)

Using points: m = (4 - 0) / (-3 - 5) = 4/-8 = -1/2

[Use point-slope formula]

(y-y0) = m(x-x0)

Using points: (y - 0) = -1/2(x - -5)

Finally: y = -1/2x -5/2

Calculation is done as follows:

Number of movie posters remaining = 120 - 24 = 96

Number of band posters remaining= x  

120:100 = 96:x

x = 80  

100-x = 100 - 80 = 20

So, she should sell about 20 band posters for her to maintain the same ratio of the movie posters to the band posters.

Answers

Answer:

You can't make a point=slope form equation.

Step-by-step explanation:

The vertical line would be parallel to y- axis, hence its equation would be x= c . The slope of the vertical line is undefined, therefore there is no point slope form as such.

BRAINLIEST!!!!!!!!!!!!!!The Online Child Parents should seriously think about the online life of their children. "Online life" refers to the activities people are involved in while using the Internet. Today's teenagers have grown up with technology and the Internet. They are becoming more knowledgeable about technology, sometimes more so than their parents. These days, teenagers spend a lot of their time on the Internet using social networking sites. Other times, teenagers enjoy spending time with their school friends or playing sports. Social networking sites provide the perfect place for teenagers to exercise their freedom. In addition, these teenagers also find a venue to express themselves openly with their online friends. They post pictures of themselves and share thoughts for the whole world to see. The problem is that the teenagers are not always aware that their images and words on the Internet are permanent. Teenagers may not be aware that people often use fake identities on the Internet and give false information. In addition, problems with "friends" on the Internet can have real-life consequences. And just like a real child, the online child needs the parents to tell him or her how the world (of the Internet) works. The teenagers need to learn critical-thinking skills applicable to real life and Internet life. While educating their children on the risks of the Internet, parents should also demonstrate trust and allow their children enough space to learn on their own. For example, parents can let their children know that they will be making frequent checkups on their children's social networking page. That way, children can learn to practice caution when they post content on the Internet, while still retaining a feeling of independence. Parents can take the check-up time to teach their children about safe online habits.Which sentence could be added to the end of the introduction to strengthen it? A.
