The value of x is 20°

According to the question we have been given two parallel lines which is cut by a transversal line. There are total 8 angles and given is the measure of

∠4 = 5x + 35° and ∠7 = 45°.

We need to find the value of x.

Note that when two parallel lines are cut by a transversal then

i) corresponding angles are equal that is

                ∠1 = ∠5, ∠2 = ∠6, ∠3 = ∠7, and ∠4 = ∠8

ii) alternate interior angles are equal that is

                 ∠3 = ∠6, and ∠4 = ∠5

iii) alternate exterior angles are equal that is

                ∠1 = ∠8, and ∠2 = ∠7

iv) Consecutive interior angle sum is 180°

          ∠4 + ∠6 = 180°, and ∠3 + ∠5 = 180°.

Now using these rules we will solve this problem

Because of corresponding angles ,  ∠3 = ∠7 = 45°

Also ∠3 and ∠8 make a linear pair and sum of linear pair is 180°.

Therefore ,  ∠3 + ∠8 = 180°

                   45° + 5x + 35° = 180°

                     5x = 180° - 80°

                      x = 20°

Hence the value of x is 20°

Answer:

3x - 1 = 6x - 7

x = 2

Explanation and Check part below

Hope this helps :)

Step-by-step explanation:

1. To solve it, first get the variable on same side.

3x - 1 = 6x - 7

- 3x - 3x

- 1 = 3x - 7

2. Isolate the variable by doing the inverse operation which is in this case addition (adding 7).

- 1 = 3x - 7

+ 7 + 7

6 = 3x

3. Isolate variable by doing the inverse operation which is in this case division (dividing by 3).

6 = 3x

3 3

2 = x

OR

x = 2

Check:

1. Substitute x with 2 and solve.

3(2) - 1 = 6(2) - 7

6 - 1 = 12 - 7

Answer: Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.

The height of the rectangular pyramid tent's center pole = 5.5 feet.

Volume of rectangular pyramid = 1/3(length)(width)(height).

Given the following:

Substitute

88 = 1/3(8)(6)(height)

88 = 16(height)

88/16 = height

5.5 = height

Therefore, the height of the rectangular pyramid tent's center pole = 5.5 feet.

Answer:

Step-by-step explanation:

We can tell if a triangle can exist based on the relationship between the side lengths.

Side Length Relationships

For a triangle to really exist, the sum of the smaller legs must be greater than the length of the longest leg. This can be expressed with the inequality a + b > c, where a and b are the shorter legs.

Now, we can plug the values we are given into this inequality.

Since the inequality is true, this triangle does exist.

Other Examples

One of the most important things to remember is that the sum of the shorter legs must be greater than, not equal to, the longest leg. So take the sides 4, 6, and 10.

This statement is not true. 10 is not greater than 10; they are equal. Thus, these sides cannot make a triangle.

Additionally, if the 3 numbers are Pythagorean triples, then it will be a right triangle. For example, the sides 5, 12, and 13 will create a right triangle.

The proof for the decimal expansion d₁d₂d₃d₄.... is evaluated.

A number's decimal expansion is its base-10 representation (i.e., in the decimal system).

Now, as per the given question;

We focus on non negative decimal expansions as well as nonnegative real numbers. Every nonnegative decimal expansion, in our opinion, is short form for the limit of a constrained increasing sequential manner of real numbers.

Assume we're given a decimal expansion K. d₁d₂d₃d₄.... where K is a non-negative integer and each value of dj belongs to {0,1,2,3,4,5,6,7,8,9}.

Then Sn is defined as the increasing sequential of real numbers and Sn is also restrained by (sn < k + 1) .

Using Theorem; converges to a real number, which we usually write as K. d₁d₂d₃d₄....

Like. 3.33333 can be written as;

[tex]\lim _{n \rightarrow \infty}\left(3+\frac{3}{10}+\frac{3}{10^2}+\cdots+\frac{3}{10^n}\right)[/tex]

We use the following geometric series fact to calculate this limit:

[tex]\lim _{n \rightarrow \infty} a\left(1+r+r^2+\cdots+r^n\right)=\frac{a}{1-r} \quad \text { for } \quad|r| < 1 .[/tex]

Where a =3 and r = 1/10.

Similarly, for 0.9999.....it can also be written as

[tex]\lim _{n \rightarrow \infty}\left(\frac{9}{10}+\frac{9}{10^2}+\cdots+\frac{9}{10^n}\right)=\frac{\frac{9}{10}}{1-\frac{1}{10}}=1 .[/tex]

Extreme values have little impact on the median and quantiles because they all come inside the middle half of the data.

Calculation:

Let’s assume the 24 students in the room range in age from 185, 185, 186, 186,.... 195, 195, 196, 196 months.

The total of x2 is 871252.

The sum of x is 4572.

The mean is 190.5 (4572/24).

The median, which lies between positions 12 and 13, is 190.5.

Standard deviation is (871252/24 -190.52)^0.5 = 3.45

Halfway between the( 18th and 19th)- (6th and 7th)interquartile range

= 6 (193.5 - 187.5).

Include his age of 716 months in the calculations as the teacher now.

Total x2 = 1383908

Total x = 5288

Mean (5288/25) = 211.52

Median (13th) = 191

Standard Deviation is (1383908/25 - 211.522)^0.5 = 103.03

Interquartile range (7th minus 19th) is 194 - 188 = 6

Therefore the mean has changed by 21.02 after the addition of a piece of data that is vastly different from the rest, yet the median has changed by only 0.5.

The interquartile range has remained constant, whereas the standard deviation has increased by over 100 and by a factor of approximately 30.

We get the perimeter of the circle as 87.92 m and area of the circle as 615.44 m².

We are given the radius of the circle as:

Radius = r = 14 m

We are also given the value of π as:

π = 3.14

We need to find the perimeter and area of the circle.

Perimeter of the circle is given by:

Perimeter = 2 π r

Substituting the values in the formula, we get that:

P = 2 × (3.14) × (14) m

P = 87.92 m.

Area of the circle is given by:

Area = π r²

Substituting the values in the formula, we get that:

Area = (3.14) × (14)²

A = 615.44 m²

The slope is 4 and point on the line is origin (0,0).

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

Given:

The equation of the line is

y+4=4(x-2)

We have to find the slope and point on the line.

y+4=4(x-2)

y+4=4x-8

Substract 4 from both sides we get,

y=4x-12

Since the equation now is in y = mx + b form, we can identify the slope m=4 and the y-intercept b=-12 and point on the line origin (0,0).

Therefore, the slope is 4 and point on the line is origin (0,0).
