help please!! I'm very confused

Answer:

3rd shape as it hase 9 sides

Step-by-step explanation:

1260/ 180 =7

7+2 = 9 sided shape

The polygon with 9 sides has an interior angle sum of 1280º.

Hence, option c is true.

We have to give that,

In a polygon an interior angle sum of 1280º.

We know that,

The formula for calculating the sum of interior angles is,

( n − 2 ) × 180°

where n is the number of sides.

Here, an interior angle sum of 1280º

Hence,

(n - 2) × 180° = 1280°

Divide both sides by 180°

(n - 2) = 1280/180

n - 2 = 7

n = 7 + 2

n = 9

So, The polygon with 9 sides has an interior angle sum of 1280º.

Answer:

x = 5

Step-by-step explanation:

Since the triangles are similar, corrresponding sides are in proportion.

[tex]\frac{NM}{SR} = \frac{ML}{RL} = \frac{NL}{SL}[/tex]

Using the equation formed by the second and third fraction above we get

[tex]\frac{28}{24} = \frac{3x - 1}{x + 7}[/tex]

28(x + 7) = 24(3x - 1)

28x + 196 = 72x - 24

44x = 220

x = 5

Answer:

X = 7

Step-by-step explanation:

180=90+4x+6+8x

84=12x

7=x

Answer:

x = 7

Step-by-step explanation:

The 3 angles in a triangle sum to 180°

sum the 3 angles and equate to 180

90 + 8x + 4x + 6 = 180 , that is

12x + 96 = 180 ( subtract 96 from both sides )

12x = 84 ( divide both sides by 12 )

x = 7

Answer:

e= -10/9

Step-by-step explanation:

Answer:

e = 10

Step-by-step explanation:

1.) We need to manipulate the equation to get e by itself.

2.) To solve the equation, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e (Combine like terms)

9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)

e + 4 = 14 (Combine like terms)

e + 4 - 4 = 14 - 4 (Subtract 4 from each side)

e = 10 (Combine like terms.

3.) Answer: e = 10.

Now lets check our work. To check your work, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e

9(10) + 4 = 14 + 8(10)

90 + 4 = 14 + 80

94 = 94

By doing those steps we can confirm the answer, e = 10, is true.

Answer:

The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.

In a right triangle, one of the angles has a value of 90 degrees.

The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.

Answer:

Step-by-step explanation:

2)  r = 16/2 = 8 cm

Area of top and bottom = 2*πr²

                                        = 2 * 3.14 * 8 * 8

                                       = 401.92 cm²

Midlle part = h * πd

                 = 6 * 3.14 * 16

                = 301.44 cm²

Total = 401.92 + 301.44

        =        703.36 cm²

3) Area of front and back = [tex]2* \frac{1}{2}*b * h\\[/tex]

                                         [tex]= 2*\frac{1}{2} * 3 * 4\\\\= 12 cm^{2}[/tex]

Area of bottom = length * breadth

                           = 12* 3

                          = 36 cm²

Area of left =  12 * 4

                  = 48 cm²

Area of right = 12 * 5 = 60 cm²

Total = 12 + 36 + 48 + 60 = 156cm²
