[tex]sum \: of \: angles\: of \: a \: polygon \: = \\(n - 2) \times 180\degree[/tex]

in the question , we've been given a five sided figure , i.e. , a pentagon.

sum of angles of a pentagon = ( 5 - 2 ) × 180°

[tex]\implies \: 3 \times 180\degree \\ \implies \: 540\degree[/tex]

thus we can say that ,

angle sum property of pentagon states that the sum of all the angles of a pentagon equals 540°.

therefore ,

Step-by-step explanation:

[tex]125\degree + 117\degree + (x + 6)\degree + x + (x - 44)\degree = 540\degree \\ \\ 125\degree + 117\degree + x + 6\degree + x + x - 44\degree = 540\degree \\ \\ 204\degree + 3x = 540\degree \\ \\ 3x = 540\degree - 204\degree \\ \\ 3x = 336\degree \\ \\ x = \cancel\frac{336}{3} \\ \\ x = 112\degree[/tex]

To find :-

The value of x in the angles of Pentagon

Given :-

Here we have been provided 5 angles in Pentagon

x°, (x - 44)°, (x + 6)°, 125°, and 117°

Solution :-

We will find the value of x with the angle sum property.

Now, we will find the sum of angles of Pentagon

there is a formula

(n - 2) × 180°

n = no. of sides of above shape

here n = 5

(5 - 2) × 180°

3 × 180° = 540°

Now will add the above given angle in the diagram and put equal to 540°.

x° + (x - 44)° + (x + 6)° + 125° + 117° = 540° (angle sum property)

[tex]3x + 204{\degree} = 540{\degree} \\ 3x = 540{\degree} -204{\degree} \\ 3x = 336{\degree} \\ x = \frac{336{\degree}}{3} \\ x = 112{\degree}[/tex]

x = 112°

further we will find further 2 angles related to x.

x - 44 = 112 - 44 = 68°

x + 6 = 112 + 6 = 118°

Result :-

The all angles of Pentagon are

125°, 117°, 118°, 112°, and 68°.

Answer:

30

Step-by-step explanation:

I see that the square in the triangle is a right triangle, so it's automatically a 90 degrees. the triangle should add up to 180, so I figured that since we have 90, we just needed to find the other angles that help add up to that, which is 60 and 30

Answer:

108 cm^2

Step-by-step explanation:

rectangle   + 2  triangle = total area

L x W          + 2    *  1/2 base * height   = total area

(5x12)          + 2    *  1/2 * 12 * 4    = total area

  60              +   48    = 108 cm^2

Answer:

108 cm²

Step-by-step explanation:

To do:

1. find area of rectangle      2. find area of triangles       3. add them together

area of a rectangle = bxh = 5x12 = 60

area of triangle = (bxh)/2 = (12x4)/2 = 24

60+24+24=108

Answer: 2.8

Step-by-step explanation: 80/100 of 14 = 11.2

Wrong = 14 - 11.2

Answer:

You got 11.2 questions right and 2.8 questions wrong.

Step-by-step explanation:

80% * 14 is 11.2

And 14-11.2 is 2.8

Step-by-step explanation:

m = 14, n = 12.5

m<L = (5m + 36)° = (5(14) + 36)°

L = 106°

m<p= (6n-1°)=(6x12.5-1°)

p=74°

m<Q = (4m + 50)° = (4(14) + 50)°

Q = 106°

k=360°-(106°+74+°106°)=360°-286°

k=74°

The sum of the interior angle of a parallelogram is 360°

The opposite side of a parallelogram are equal.

The balance in Hayden's savings account is $600.

Net worth is total assets less liabilities. Assets are items owned by a person that creates benefits in the future to the person. Liabilities are what are owed to another person.

Net worth = assets - liabilities

6760 = (2540 + 6000 + savings)  - (880 + 1500)

6760 = 8540 + savings - 2380

Savings = 6760 - 8540 + 2380

Before reaction, total number of nitrogen atoms is 2, also the total hydrogen atoms is 6. After the reaction, still, we have the same number of nitrogen atoms as 2, and hydrogen atoms as 6. This therefore obeys the law of conservation of mass that during a chemical reaction, matter is neither created nor destroyed.

This equation has no solution. You have one equation with two variables, so it cannot be solved. If you have another equation having the same variables x and y, then by using simultaneous equations, values of x and y can be solved. But to this equation 4x + 5y = 6, there is no solution for the reason mentioned above.

Answer:The slope of linear function is same for all pair of points on line.

Step-by-step explanation:

Using it's concept, it is found that there is a 0.5 = 50% probability that the second letter is an A.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, we consider that:

Hence, the total number of words is:

T = 3 x 2 x 2 = 12.

With the second letter being A, the number of words is:

D = 3 x 1 x 2 = 6.

Hence, the probability is given by:

p = 6/12 = 0.5.

Answer:

The rectangle:  L = 40 yards.   W = 5 yards

The square: The length and width are both 5 yards.

Step-by-step explanation:

Let L and W be the length and width of the rectangle.

Let l and w be the length and width of the square.

Area for each is:

Rectangle:  L*W

Square:       l*w

We are told that L*W + l*w = 225 yards^2

We are also told that

L = 8W

and that

l = W

Since the sides of a square are all equal, w is also W:  w=W

Summarizing and substituting:

L*W + l*w = 225 yards^2

(8W)*W + W*W = 225 yards^2

8W^2 + W^2 = 225 yards^2

9W^2  = 225 yards^2

W^2 = 25

W = 5 feet

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

Therefore, since L = 8W , L = 40 yards.   W = 5 yards for the rectangle.

The square:  l=W, so l = 5 yards, and thus w=5 yards

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