Answer:

obtuse scalene      give crdit to the answer above

For example, all equilateral triangles are similar and all squares are similar. If two polygons are similar, we know the lengths of corresponding sides are proportional. In similar polygons, the ratio of one side of a polygon to the corresponding side of the other is called the scale factor.

Answer:

A. 2a+6b

B. a+(a+6b)

D. a + 3b

E. 2a+(5+1)b

Step-by-step explanation:

Given:

2(a + 3b)

Open parenthesis

= (2a + 6b)

A 2a+6b

B. a+(a+6b)

= a + a + 6b

= 2a + 6b

C 2b+3a

Not equivalent

D. a + 3b

2a + 6b

Divide through by 2

= a + 3b

E. 2a+(5+1)b

= 2a + (6)b

= 2a + 6b

F. a2+b5

Not equivalent

Answer:

9

Step-by-step explanation:

To solve this, you need to find the proportion.

p is a leg of the large triangle, and the leg to the small triangle is 6.

8 is another leg of the small triangle, and 8+4 is the leg of the large triangle.

So [tex]\frac{small triangle}{big triangle} = \frac{small triangle}{big triangle\\}[/tex]

[tex]\frac{8}{12} =\frac{6}{p}[/tex]

[tex]\frac{2}{3} =\frac{6}{p}[/tex]

cross multiply to get 2p=18

divide both sides by 2

p=9.

Answer:

[tex]x = 9[/tex]

[tex]y = 17[/tex]

Step-by-step explanation:

This is a cyclic quadralterial so opposite angles are supplementary.

The x variables add up to 180 so

[tex]11x + 8 + 8x + 1 = 180[/tex]

[tex]19x + 9 = 180[/tex]

[tex]19x = 171[/tex]

[tex]x = 9[/tex]

The y variables add up to 180.

[tex]6y - 4 + 5y - 3 = 180[/tex]

[tex]11y - 7 = 180[/tex]

[tex]11y = 187[/tex]

Answer:

u = 23 and t = 6

Step-by-step explanation:

Given

u = 4v - 3t

(a)

u = 4(5) - 3(- 1) = 20 + 3 = 23

(b)

- 10 = 4(2) - 3t

- 10 = 8 - 3t ( subtract 8 from both sides )

- 18 = - 3t ( divide both sides by - 3 )

6 = t

Answer:

12.16

Step-by-step explanation:

From your question, we have the following information

Mean = u = 20

Standard deviation sd = 4

P(X>Xo) = 0.975

1-0.975 = 0.025

P(z<Xo-20/4) = 0.025

Xo-20/4 = -1.96

We cross multiply

Xo - 20 = -1.96 x 4

Xo - 20 = -7.84

Xo = -7.84+30

Xo = 12.16

12.16 is the value of Xo and therefore the answer to this question.

we know that a whole circle is found using π[tex]r^{2}[/tex].

So π[tex]10^{2}[/tex] = 314

so now we know that the whole circle is 314 squared units, we need to find the specific portion.

Oh wait, i learned this lol,

formula for area of sector

As (areas of sector) = π[tex]r^{2}[/tex]([tex]\frac{θ}{360}[/tex])

As (areas of sector) = π[tex]10^{2}[/tex]([tex]\frac{θ}{360}[/tex])

100 times 3.14

314 (43/360)

314(0.12)

As (areas of sector) = 37.68

I hope this finds you well, and have a great day.

Answer:

Radius of the cylinder = 1.69 units

Step-by-step explanation:

Volume of a cylinder is given by the expression,

Volume = Area of the circular base × Height of the cylinder

Area of the circular base = πr²

Here, r = Radius of the circular base

Volume of the cylinder = πr²h

By substituting the values given in the question,

72 = π(r)²8

r² = [tex]\frac{9}{\pi }[/tex]

r² = 2.865

r = 1.692

r = 1.69 units

Answer:

Step-by-step explanation:

4) Angles opposite to equal sides are equal

45 + 45 + x = 180     {Angle sum property}

        90 +x = 180       {Subtract 90 from both sides}

               x = 180 - 90  

               x = 90

120 +y + y = 180        {Angle sum property}

      120 +2y = 180       {Subtract 120 from both sides

              2y =180 - 120

               2y = 60      {Divide both sides by 2}

                 y = 60/2

y = 30

5)All sides are equal. so this is a equilateral triangle.

So each angle of equilateral triangle = 60

4x = 60

x = 60/4

x = 15

y = 60 +60   {Exterior of triangle equal sum of opposite interior angles}

y = 120

6) All sides are equal. so this is a equilateral triangle.

So each angle of equilateral triangle = 60

y - 10 = 60    {add 10 to both side}

y = 60 + 10

y = 70

x + 5 = 60    {Subtract 5 from both sides}

x = 60 - 5

x = 55
