Answer:

Traversals, Eh?

2-99 degrees

3-81 degrees

4-81 degrees

Step-by-step explanation:

So to find the measures of these angles, we need to find the relationship between these angles.

1 and 2 are Alternate Exterior angles(Maybe, been a while since I have done traversals).

They are supplementary angles the sum of their measurements is 180

180=<1+<2

So, I'll spare the math and let you figure out how I got it.

<2=99 degrees

1 and 3 are vertical angles, meaning they have got the same angle measure.

So, <3 is 81 degrees

1 and 4 are Corresponding Angles, meaning they have the same angle measure.

So, <4 is 81 degrees

Hope This helps!

P.S. Google the Names of the angles, I might be wrong!

Answer:

2: 99° 3: 81° 4: 81°

Step-by-step explanation:

2 is supplementary to 1 so subtract 81 from 180 = 99.

3 is vertical angle with 1 so they are equal

4 is alternate interior angle with 3 so they are equal

hope this helps stay safe :)

Translate into an algebraic expression and simplify if possible. I have a total of 10 gigabytes of data on my computer, xgigabyt

pogonyaev

Answer:

(20-3x)/2 GB

Explanation:

Total amount of data on my computer = 10GB

Total amount of data occupied by movies = x GB

If pictures take up half the amount of space that movies do, then;

Total amount of data occupied by pictures = 1/2 of space occupied by movies = 1/2 x

If the remaining are music, the amount of space occupied by music will be expressed as shown;

Total space -(space occupied by movies + space occupied by pictures)

= 10 - (x+1/2 x)

Total amount of data occupied by music = 10 - (x+1/2 x) GB

On simplification;

= 10 - (x+1/2 x)

= 10-{(2x+x)/2}

= 10 - {3x/2}

= (20-3x)/2 GB

Hence, amount of gigabytes of music stored on my computer is expressed as (20-3x)/2 GB.

Jeremy wants to determine the number of solutions for the equation below without actually solving the equation.

Degger [83]

Answer:

1 solution

Step-by-step explanation:

Jeremy can simplify the equation enough to determine if the x-coefficient on one side of the equation is the same or different from the x-coefficient on the other side. Here, that simplification is ...

-3x -3 +3x = -3x +3 +3

We see that the x-coefficient on the left is 0; on the right, it is -3. These values are different, so there is one solution.

In the attached, the left-side expression is called y1; the right-side expression is called y2. The two expressions are equal where the lines they represent intersect. That point of intersection is x=3. (For that value of x, both sides of the equation have a value of -3.)

<em>Additional comment</em>

If the equation's x-coefficients were the same, we'd have to look at the constants. If they're the same, there are an infinite number of solutions. If they are different, there are no solutions.
