Perimeter of polygon is 96 inches

Area is 192 square inch.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

Given,

Perimeter = sum of all sides

Perimeter = 8 + 10 + 10 + 18 + 12 +12 +8+ 10 + 10+8 + 10

Perimeter = 86

Answer:

Five dollars?

Step-by-step explanation:

I don’t fully understand the question, so apologies if I am incorrect!

The statement is true. Multiplication is commutative, which means that the order of multiplication does not affect the result.

The statement "0 x 5 = 5 x 0" is true because of the commutative property of multiplication. In multiplication, the order of factors does not change the result.

When we multiply 0 by 5, it equals 0 since anything multiplied by 0 is 0. Similarly, when we multiply 5 by 0, the result is still 0. Both expressions are equal to 0, confirming the commutative property.

In summary, 0 x 5 and 5 x 0 are interchangeable and yield the same result, proving the truth of the statement based on the fundamental property of multiplication.

The value of x in the triangle is 46.40° .

The angle of a triangle can be found using sine rule.

Therefore, applying sine rule,

a / sin A = b / sin B = c / sin C

Hence,

5 / sin x = 6.9  / sin 88°

cross multiply

5 sin 88° = 6.9 sin x

5 × 0.99939082701 = 6.9 sin x

4.9969541351 = 6.9 sin x

divide both sides by 6.9

sin x = 4.9969541351  / 6.9

sin x = 0.72419625146

x = sin⁻¹ 0.72419625146

x = 46.4020264383

Therefore,

x = 46.40°

An element of a line known as a line segment joins two places that are thought of as line's ends. Point C is on line segment BD, Given CD = 2 and BC = 8, the length BD is 10.

A line segment in geometry is a section of a straight line that is enclosed by two clearly defined end points and contains all of points on the line that lie inside those endpoints. The Euclidean distance between the two ends of a line segment determines its length. Half-open line segments contain exactly one of endpoints, while closed line segments have both of the endpoints. Open the line segments do not contain either of the endpoints. A line drawn above the symbols for the two endpoints is frequently used in geometry to indicate a line segment.

An element of a line known as a line segment joins two places that are thought of as line's ends. It is possible to measure the separation between two places. Given that line segments have a defined length, they can form the sides of any polygon.

Given:

a.) Each small box of paper weighs 50 pounds.

b.) Each large box of paper weighs 80 pounds.

c.) There were 4 more large boxes shipped than small boxes.

d.) The total weight was 1750 pounds.

Since the scenario is involving two types of boxes, we will be using two variables to represent each of them.

Let,

x = the total number of the small box of paper

y = the total number of the large box of paper

Let's now generate the system of equations that we will be using to able to solve the problem.

1st relationship: There were 4 more large boxes shipped than small boxes.

Putting this into equation, we get:

2nd relationship: The total weight was 1750 pounds.

For us to get the total weight, we will be adding the sum of the number of each box by the weight each box has.

We get,

In summary:

Let x = the total number of the small box of paper

Let y = the total number of the large box of paper

System of equations:

a.) y = x + 4

Answer:

The height of pole is 20√3 m each and distance of pole from the point on road is 60 m and 20 m respectively.

Step-by-step explanation:

Given:

To Find:

Formula used:

Let the height of each pole be H metres.

Also, let's assume that distance of the point from one pole (as shown in figure) be x m.

According to question, we have

tan60° = H/(80-x)

H = (80-x)√3.... (1)

Also, tan30° = H/x

H = x/√3... (2)

Putting value of eq(2) in eq(1), we get

x/√3 = (80-x)√3

x = 3(80-x)

x = 240 - 3x

4x = 240

x = 60 m

Putting value of x in eq(2), we get

H = 60/√3 = 20√3 m

So, the height of pole is 20√3 m each and distance of pole from the point on road is 60 m and 20 m respectively.

Answer:

Height of Pole: 20√3 m

Distance Of Point From Poles: 20m and 60m

Step-by-step explanation:

The attached graph may help you understand my explanation better

The two poles are Ab and CD and are 80m apart

O is the point between them

The angle of elevation from O to A is 60°

The angle of elevation from O to D is 30°

Since the two poles are given to be of equal height,

AB = CD

In ΔAOB using the law of tangents

tan 60° = AB/BO

tan 60° = √3 and AB = x

So we get

√3 = x/BO

Multiplying both sides by BO we get

√3 · BO = x

or BO = x/√3

Looking at ΔCOD

tan 30° = DC/OC

tan 30° = 1/√3

1/√3 = x/OC

OC · ( 1/√3) = x

OC = x ÷ 1/√3

= x · √3/1

OC = √3x

We also know that BO + OC = 80

Plugging this information with values computed gives us

x/√3 + √3x = 80

Multiply by √3 on both sides

(x/√3) · √3 +  (√3x) √3 = 80√3

(x/√3) · √3 = x since the √3 terms cancel out

(√3x) √3 = 3x

So we get

(x/√3) · √3 +  (√3x) √3 = 80√3

=>
x + 3x = 80√3

4x = 80√3

x = (80√3)/4

x =20√ 3

So the height of each pole = 20√ 3 m ≈ 34.64 m

The distance OC can be found from the previous equation
OC = √3x

=> OC = √3 x 20√3 = 20 x 3 =  60m

Since BO + OC = 80 m

BO = 80 - 60 = 20 m

Answer:
Height of each pole = 20√3 m

The point is located 20 m from one pole and 60 m from the other pole

As you see the picture the number is 1.249

step 1

As you know before decimal the digits are said to be ones,tens, hundred so on and starts from left to right.

But after decimal it goes right to left and they are said ones,tenth,hundredth

step 2

so here it says 1 decimal place means ones means one digit after dot or point so its 2

The number rounded off to 1 decimal place is 1.2

Rounding is a process to estimate a particular number in a context. To round a number look at the next digit in the right place, if the digit is less than 5, round down and if the digit is 5 or more than 5, round up. Rounding decimals refer to the rounding of decimal numbers to a certain degree of accuracy.

Given here, the number is 1.249 and thus the number rounded upto 2 decimal place is 1.25 and further rounding up the number to one decimal place we get 1.2

The value of z in this convex polygon is equal to 66°

A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides.

Note: The number of sides (n) of a pentagon is 5.

In Geometry, the sum of all the interior angles of a polygon with "n" sides is given by this formula:

Interior angle = 180 × (n - 2)

Interior angle = 180 × (5 - 2)

Interior angle = 180 × 3

Interior angle = 540°.

Now, we can determine the value of z as follows:

(180° - 2z) + (180° - z) + 130° + 108° + 140° = 540°

3z - 378° = 540° - 360°
