Answer:

8-sided polygon:  octagon

Step-by-step explanation:

The formula for calculating the sum of interior angles of a polygon is:

(n − 2) × 180° (where n is the number of sides)

Therefore,

⇒ (n − 2) × 180 = 1080

⇒ n - 2 = 6

⇒ n = 8

Therefore, the polygon is 8-sided:  octagon

The polygon that has an interior angle sum of 1080° is an octagon.

To find the interior angle sum of an octagon, we can use the formula: (n - 2) * 180°, where n represents the number of sides (or vertices) of the polygon.

An octagon is a polygon with eight sides and eight angles. To determine the interior angle sum of an octagon, we use the formula (n - 2) * 180°, where n represents the number of sides.

In this case, for an octagon, the calculation is (8 - 2) * 180° = 6 * 180° = 1080°.

For an octagon, n = 8, so the interior angle sum would be (8 - 2) * 180° = 6 * 180° = 1080°.

Thus, an octagon has an interior angle sum of 1080°.

Answer:

[tex]\huge\boxed{\sf{6x+15}}[/tex]

Step-by-step explanation:

Hello.

Let's solve this problem.

First, multiply 2 times 3x:

6x

Now, add 7 plus 8:

15

Write the expression:

6x+15

Can this expression be simplified any further?

No.

Why?

Because variables and constants are not like terms.

In this case, the variable is x, and the constant is 15.

I hope it helps

Answer:

Step-by-step explanation:

A and B are both equal (corresponding parts)

A = B

5x - 5 = 3x + 13               Add 5 to both sides

5x = 3x + 13 + 5              Combine

5x = 3x + 18                    Subtract 3x from both sides

5x - 3x = 18                     Combine

2x = 18                            Divide by 2

2x/2 = 18/2

x = 9            

Angle B

B = 3x + 13                      Let x = 9

B = 3*9 + 13

B = 27 + 13

Angle B = 40

What's easier for me is this.. 125 * 10 is 1250

Now there is 625 left to the problem is 625/125

Then I do 125 + 125 + 125 + 125 + 125 (Adding it 5 times so that I can see when it hits 625 is easier than dividing for me)

So you take the 10 from the first part and the 5 from the second part (Got the 5 because you added it 5 times)
10 + 5 is 15

Answer:

1/15

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator

GCD of 125 and 1875 is 125

Divide both the numerator and denominator by the GCD

125 ÷ 125

1875 ÷ 125

Reduced fraction:

1/15

Therefore, 125/1875 simplified to lowest terms is 1/15.

Step-by-step explanation:

A triangle's angles have to equal to 180 degrees , so option B is not a triangle because it equals to 175

Answer:

A. Triangle? Yes. How do I know? Triangles add up to 180 degrees, and the angles measures add up to 180.

B. Triangle? No. How do I know? The angle measures only add up to 175 degrees, so it can’t be a triangle.

C. Triangle? Yes. How do I know? A triangle = 180 degrees and the angle measures add up to 180.

 [tex]\frac{144}{2025}[/tex]

Step-by-step explanation:

( 3 a b ) ² = 9 a² b²

Given that,

a = - [tex]\frac{1}{5}[/tex]

b = - [tex]\frac{4}{9}[/tex]

Now you have to replace a and b with - [tex]\frac{1}{5}[/tex] and  - [tex]\frac{4}{9}[/tex] respectively.

Let us solve now.

9 a² b² = 9 × ( - [tex]\frac{1}{5}[/tex] ) ² × ( - [tex]\frac{4}{9}[/tex] ) ²

             = 9 × [tex]\frac{1}{25}[/tex] × [tex]\frac{16}{81}[/tex]

Every book is 17 centimeters tall/long.

A : If the board is the same length as 21 books, its length is 17 x 21 = 357 centimeters.

B : 357 centimeters = 3.57 meters

Since 3.57 > 3.5, the board is long enough.

Step-by-step explanation:

Angle 1: (I solved this one last) 69 degrees :) . Because Angle 2 is 37 and we know the other existing angle is 74 we can do 74+37 and subtract that from 180.

Angle 2: 37 degrees. Because Angle 2 and the 53 degree angle add up to a right triangle (90 degrees) you can subtract 90-53 and get 37.

Angle 3: 106 degrees. Because the line is a straight line, all angles should add up to 180 degrees, and 180-74=106.

Angle 4: 21 degrees. Because we know that Angle 3 is 106 degrees, we can do (106+53) and then subtract from 180 because all angles in a triangle should equal 180 degrees.
