Answer:

Step-by-step explanation:

This is basically a vocabulary question. Angle pairs around a transversal crossing a pair of parallel lines all have names. Those names are used to refer to different theorems about the relationships of the angles to each other. Once you understand the words being used, the vocabulary is easier to remember.

Angles formed where one line crosses another form a linear pair if they share a side and the non-shared sides are opposite rays. If they share a vertex, but not a side, they are vertical angles. The angles of a linear pair are supplementary: they total 180°. Vertical angles are supplementary to the same angle, so vertical angles are congruent. These relations hold anywhere lines cross.

__

Where a single line crosses two (parallel) lines, that line is called a "transversal". Four angles will be formed at each intersection. Some of those angles are between the (parallel) lines, so are referred to as interior angles. The ones that are not between the (parallel) lines are referred to as exterior angles. The angles are alternate if they are on opposite sides of the transversal, and they are consecutive, or same-side if they are on the same side of the transversal.

Angles that lie in the same direction from the crossing point (to the northeast, for example) are corresponding angles.

__

In your figure, we can identify the following pairs:

The theorems referenced above will tell you if and only if the lines are parallel ...

____

Using the above, we find the answers to your questions to be ...

  1. (a, f) - corresponding angles (b)

  2. (b, h) - alternate interior angles (a)

  3. (h, g) - vertical angles (d)

  4. (c, g) - alternate exterior angles (c)

  5. (a, c) - supplementary angles (e)

  6. (e, i) - corresponding angles (b)

_____

Additional comment

In the above, we put (parallel) in parentheses, because these same definitions apply where the crossed lines may not be parallel. The relevant angle relationships can be used to determine if the lines are parallel or not. For example, if "corresponding" angles are congruent, the lines will be parallel. If "consecutive interior" angles do not total 180°, the lines cannot be parallel.

These same relationships hold in geometric figures, such as rectangles, trapezoids, parallelograms. For example, each side of a parallelogram is a transversal crossing a pair of parallel lines (the adjacent sides). Sometimes, you're asked to prove particular angle relationships in these figures. You can often do so by making use of the angle theorems related to parallel lines.

Answer:

B: Acute

Please make me brainiest

Answer:

B) ∠B

Step-by-step explanation:

We'll name the given acute angle as either ∠ABC or ∠B. This is because, 'B' is the vertex of the given angle, i.e., AB & AC share the same common point → 'B'. Hence, ∠B is the correct option.

==========================================

Explanation:

The 102 inscribed angle cuts off the arc that's composed of the 140 and 'a'.

Due to the inscribed angle theorem, we know that a+140 is exactly equal to twice that of 102.

This means,

a+140 = 2*102

a+140 = 204

a = 204-140

a = 64

-----------------

The angles 102 and c are inscribed angles opposite one another. They add to 180. This is true for any inscribed quadrilateral.

c+102 = 180

c = 180-102

c = 78

-----------------

Another useful rule is that the four angles of any quadrilateral always add to 360.

102+92+c+d = 360

102+92+78+d = 360

272+d = 360

d = 360-272

d = 88

-----------------

The inscribed angle d cuts off the arc a+b

This means 2d is the measure of a+b because of the inscribed angle theorem.

a+b = 2d

64+b = 2*88

64+b = 176

b = 176-64

b = 112

Step-by-step explanation:

All we have to do is replace s with 2.6!

V = s^3

v = 2.6^2

v = (2.6)(2.6)(2.6)

v = 6.76 * 2.6

v = 17.576

3. Explanatory variable/ new brand of yeast

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments refers to what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

We are given that baker is experimenting with a new brand of yeast. He can bakes his first batch of bread using the old brand of yeast that he usually uses and a second batch using the new brand of yeast.

Since baking both batches of bread, he compares the height, texture, and taste of each batch.

The terms with the correct descriptions in the context of this scenario are;

1. control group/ first batch

2. Response variable/ height,texture,and taste

3. Explanatory variable/ new brand of yeast

Answer:

A ∆ with an exterior angle :116° & two interior angles 7x+6 & 4x

The value of angle 7x+6

we know that ,

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non adjacent interior angles of the triangle.

so,

[tex]7x + 6 + 4x= 116 \\ 11x + 6 = 116 \\ 11x = 116 - 6 \\ 11x = 110 \\ x = 110 \div 11 \\ x = 10[/tex]

so ,the measure of green angle would be

[tex]7x + 6 \\ placing \: the \: value \: of \: x \: as \: 10 \\ 7 \times 10 + 6 \\ = 70 + 6 \\ = 76[/tex]

To verify our answer ,the sum of the resultant value of green angle and 4x should be 116°(the exterior opposite angle)

so,

[tex]7x + 6 + 4x = 116 \\ 7 \times 10 + 6 + 4 \times 10 = 116 \\ 70 + 6 + 40 = 116 \\ 76 + 40= 116 \\ 116 = 116 \\ \\ hence,\: verified[/tex]

Solution:

Note that:

Simplify the equation to find x.

Substitute the value of x into the measure of the green angle.

The measure of the green angle is 76°.

I did some math and i got this

x = -2

Hello.

In order to solve the equation, we need to isolate x.

First, subtract 1 from both sides:

[tex]\mathrm{7x+1-1=8x+3-1}[/tex]

[tex]\mathrm{7x=8x+2}[/tex]

Now, subtract 8x from both sides:

[tex]\mathrm{7x-8x=8x-8x+2}[/tex]

[tex]\mathrm{7x-8x=2}[/tex]

[tex]\mathrm{-x=2}[/tex]

Now, the minus sign is the same as -1.

In order to isolate x, we need to multiply both sides by -1:

[tex]\mathrm{x=-2}[/tex]

Therefore, the answer is

[tex]\mathrm{x=-2}[/tex]

I hope it helps.

Have a nice day.

The performance rating increased by 2 points 2.04 would happen to the attitude rating.

The slope and the intercept values are given, the equation of a line can be found easily. So, it is also known as the slope and intercept form.

The standard form to represent the equation of a line is as follows:

Given

Managers at a company rate employees on performance and attitude and find that an employee's attitude depends on their performance.

They find a linear relationship and the line of best fit is y = 11. 7 + 1.02x.

The performance rating increased by 2 points what would happen to the attitude rating is;

Cube has all six faces as square. The surface area of the outside of one of the bins is 13.5 m².

The surface area of the cube is the sum of the area of all the sides of the cube. All the six sides of the cube are made of the same size square, therefore, the surface area of the cube is 6s², where s is the length of its single side.

As it is given that the melons are kept in cubic bins whose top is closed, therefore, the cubic bin will have all six sides, with the length of the side as 1.5m.

We know the formula for the surface area of the cube, therefore, the surface area of the cubic bin is equal to the surface area of the cube with side 1.5m,

[tex]\text{Surface area of the cube} = 6s^2[/tex]

                                     [tex]= 6(1.5)^2\\\\= 6 \times 2.25\\\\=13.5\rm\ m^2[/tex]

Answer:

79

Step-by-step explanation:

cuz,
x equals the number of minutes so use the y slope formula

0.10(x)+the intercept = y
0.10(350)+the intercept = 84
35+the intercept = 84
the intercept = 49
so the equation is
0.10(x)+49 = y
or
1/10(x)+49 = y
1/10(300)+49=y
30+49=y
79=y
so the answer is 79 dollars
