Find the degree measure of each angle in the triangle

Find The Degree Measure Of Each Angle In The Triangle

Answers

Answer 1

The degree measure for angle B is 28° and angle D is 62°.

We are given that:

∠ C = 90°

∠ B = ( 2 x + 10 )°

∠ D = ( 5 x + 17 )°

Now, using the angle sum property of a triangle, we get that:

∠B + ∠ C + ∠ D  = 180°

Substituting the values:

2 x + 10 + 90 + 5 x + 17 = 180

7 x + 117 = 180

7 x = 63

x = 63 / 7

x = 9

∠ B = ( 2 x + 10 )

∠ B = 2(9) + 10

∠ B = 18 + 10

∠ B = 28°

∠ D = ( 5 x + 17 )

∠ D = 5 (9) + 17

∠ D = 45 + 17

∠ D = 62°

Therefore, the degree measure for angle B is 28° and angle D is 62°.

Answers

Coordinate of X is [tex]-18[/tex]  .

Section formulas are used to find the coordinates of the point that bisects a line segment (external or internal) at a specified ratio. When a point on a line segment divides it into two line segments, the formula used to determine the coordinates of that point is called the section formula. Suppose we have a point P(x,y) that divides a line segment in the ration m : n at points marked  as A[tex](x_1,y_1)[/tex] and B [tex](x_2,y_2)[/tex] the , section formula is given by  [tex]P(x,y)=(\frac{mx_2+nx_1}{m+n} ,\frac{my_2+ny_1}{m+n} )[/tex]

It is given that coordinate of W ( -22, 0) and Y(-2,0) and X is the point which divides the line segement WY in ratio 1 : 4.

By using section's formula , we get

[tex](x,y)=(\frac{1(-2)+4(-22)}{1+4} , \frac{1(0)+4(0)}{1+4} )\\\\(x,y)=(\frac{-2-88}{5} ,\frac{0}{5} )\\\\(x,y)=(\frac{-90}{5} ,0)\\\\(x,y)=(-18,0)[/tex]

Given g(x) = 1/3 (2x-1) 2, what is the value of g(8)?

Answers

By evaluating in x = 8 we can see that the value of g(8) is 45.

How to evaluate the function g(x)?

Here we have the function:

g(x) = (1/3)*(2x - 1)^2

We want to get the value of g(8), this means that we need to evaluate the function in x = 8.

To do this, we just need to replace the variable "x" in the equation by the number 8.

We will get:

g(8) = (1/3)*(2*8 - 1)^2 = (1/3)*(15)^2 = 3*15 = 45

Step-by-step explanation:

In order to factor the polynomial [tex]\sf 4r^3 - 3r^2 - 4r + 3[/tex], we can use various factoring methods.
In this case, we can use grouping.

Let's break down the expression and factor it step by step:

Group the terms in pairs:

(4r^3 - 3r^2) +(-4r + 3)

Factor out the greatest common factor from each group:

[tex]\sf r^2(4r - 3) - 1(4r - 3)[/tex]

Notice that both groups have a common factor of (4r - 3): and keeping remaining in bracket

[tex]\sf (4r -3)(r^2-1)[/tex]

Now, the expression r² - 1 can be factored further using the difference of squares:

(r + 1)(r - 1)

So, the fully factored form of the polynomial 4r³ - 3r² - 4r + 3 is:

(4r - 3)(r + 1)(r - 1)

Here Sunil deposited $400 for one and a half years, and the interest he gets is $78. He deposits in at the simple rate of interest.

Answers

Final answer:

When two variables are correlated or associated, it does not necessarily follow that one of the variables is the root cause of the other. Correlation does not always indicate cause.

What are the three forms of mathematical correlations ?

The link between variables is described by correlation. It can be characterized as strong or weak, as well as positively or negatively.

Positive correlation occurs when two variables change in the same direction. There are three fundamental forms of correlation. The two variables fluctuate in opposite directions when there is a negative correlation. No association or meaningful connection exists between the two variables, hence there is no correlation.

The correlation coefficient aids in determining how closely two variables are related in a single figure. Finding the crucial variables that other factors depend on and comprehending economic behavior are both facilitated by correlation analysis.

Explanation:

A correlation test determines whether two variables are related. Nevertheless, just because two variables are traveling together does not necessarily mean they are connected. This is why the phrase "correlation does not indicate causation" is used frequently.

As two factors are connected or related, it does not necessarily imply that one of the variables is the main cause of the other. Correlation not always show cause.

You have to times 2 by 2 by 2 like this=8

2x2=4 4x2=8

then subtract them= 16-8= 8
put it over the line where 4 and 2 were

after you subtract 5 and 3= 2

than times 2 by the squared= 2x2= 4

times the 2 with 4= 8

put the 8 under the line so you can divide it

8 divided by 8 is 1

lastly, add 7 and 1= 8

the answer is eight

four squared is 16 and two cubed is eight so sixteen minus eight is eight then five minus three is two then you would figure out what 2 squared us and its four so two times four is eight so the first part is eight over eight which is one and one plus seven in eight

How to find the numeric value of a function/expression?

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the functions are given as follows:

f(x) = 1 - x².[tex]g(x) = \sqrt{11 - x}[/tex]

At x = -1, the values are given as follows:

f(-1) = 1 - (-1)² = 1 - 1 = 0.[tex]g(-1) = \sqrt{11 - (-1))} = \sqrt{12}[/tex]

Hence:

[tex](g - f)(-1) = g(-1) - f(-1) = \sqrt{12}[/tex][tex]\frac{f}{g}(-1) = \frac{f(-1)}{g(-1)} = \frac{0}{\sqrt{12}} = 0[/tex]

At x = 2, the values are given as follows:

f(2) = 1 - (2)² = 1 - 4 = -3.[tex]g(2) = \sqrt{11 - 2} = \sqrt{9} = 3[/tex]

A function from a set X to a set Y assigns to each element of X exactly one element of Y.

We will do this by substituting the value of x as - 1

Put x = -1, we get that:

f ( x = -1 ) = ( - 1 ) + 4 ( - 1 )³

f ( - 1 ) = - 1  + 4 ( - 1 )

f ( - 1 ) = - 1 - 4
