Answer:

sasha's is longer.

Step-by-step explanation:

Answer:

Yes.

Step-by-step explanation:

The sum of the interior angles of triangles always add up to 180 degrees. The third angle of the top triangle would be 27. The third angle of the bottom triangle is 63.

Triangles are similar if the angles are the same. Therefore the 2 triangles are similar.

Hope that this helps!

Answer:

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

Step-by-step explanation:

we have a square and a triangle

we want to figure out the area and the perimeter of the pentagon

to figure out the area of the pentagon we can use the given formula:

[tex] \displaystyle \rm A_{ \text{c - pentagon}} = A_{ \text{squre}} - A_{ \text{triangle}}[/tex]

let's figure out [tex]A_{\rm square}[/tex]:

since the given shape is a square Every angle of its 90° Thus the triangle is a right angle triangle

therefore the height is 4

[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times b \times h[/tex]

substitute h and b

[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times 4 \times 4[/tex]

reduce fraction:

[tex] \displaystyle A _{ \rm triangle} = 2 \times 4[/tex]

simplify multiplication:

[tex] \displaystyle A _{ \rm triangle} = 8[/tex]

likewise square

[tex] \displaystyle A _{ \rm squre} = {s}^{2} [/tex]

substitute s:

[tex] \displaystyle A _{ \rm squre} = {7}^{2} [/tex]

simplify square

[tex] \displaystyle A _{ \rm squre} = 49[/tex]

hence,

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =49- 8[/tex]

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]

to figure out perimeter

let's figure out hypotenuse first

[tex] \displaystyle h = \sqrt{ {4}^{2} + {4}^{2} } [/tex]

[tex] \displaystyle h = \sqrt{ 16 + 16} [/tex]

[tex] \displaystyle h = 4 \sqrt{2} [/tex]

therefore,

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 3 + 3 + 4 \sqrt{2} + 7 + 7[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 6 + 4 \sqrt{2} + 14[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

Answer:

6 glasses of water

Step-by-step explanation:

This is fairly simple as we already have the equation

x+y=10 ---> x=10-y

8x+12y=96

now substitute

80 -8y  + 12y = 96

4y= 16

y=4

if y = 4

x+4=10

x=6

Answer:

37.22

Step-by-step explanation:

Answer:

37.22

Step-by-step explanation:

Answer: 340

Step-by-step explanation:

100 - 74 = 26%

26% = .26

x * .26 = 88.4

   /.26    /.26

x = 340

check

340 * .74 = 251.6

340 - 251.6 = 88.4

7^2+18^2=49+324

49+324=373

19.31^2 would be your answer

Answer:

x = 36

Step-by-step explanation:

Given

3(2x - 5) - 2x = 3(x + 7) ← distribute parenthesis on both sides

6x - 15 - 2x = 3x + 21

4x - 15 = 3x + 21 ( subtract 3x from both sides )

x - 15 = 21 ( add 15 to both sides )

x = 36

Answer:

8(4+2)

Step-by-step explanation:

Hi there! We know that 32+16=48 so all we have to do is find a expression that equals 48. 8(4+2)=48. 8(24+8)=256. 7(4+2)=42. 7(24+8)=224. Therefore, the expression that is equivalent to 32+16 is 8(4+2).

Is there more to this question?

For the first inequality, x > -1

For the second inequality, x < -1

Step-by-step explanation:

5x - 29 > -34

add 29 to both sides

5x > -5

divide both sides by 5

x > -1

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

2x + 31 < 29

subtract 31 from both sides

2x < -2

divide both sides by 2

x < -1
