tester [92]3 years ago
5 0

<h2>Given :-</h2>

  • Length of flower bed = 7 m

  • Perimeter of boundary = 22 m

<h2>To Find :-</h2>

  • Breadth
  • Area

<h2>Solution :-</h2>

As we know that

\sf \blue{Perimeter = 2(l + b)}

  • 22 = 2(7 + b)

  • 22 = 14 + 2b

  • 22 - 14 = 2b

  • 8 = 2b

  • \sf \: \dfrac{8}{2} = b

  • \bold{\boxed{b=4}   } 
<h3>Breadth = 4 m.</h3>

Now,

\sf \orange{Area = l \times b}

  • Area = 7 \times 4

  • \sf \: Area = 28 \: {m}^{2}

Area=28\bold{ m^2  }

Please help me!!!! I don’t understand
ololo11 [35]

Answer:

<h2>m∠EFG = 126°</h2><h2>m∠GFH = 54°</h2>

Step-by-step explanation:

If ∠EFG and ∠GFH are a linear pair, then m∠EFG + m∠GFH = 180°

(look at the picture).

We have

m∠EFG = 5n + 16

m∠GFH = 2n + 10

Substitute:

(5n + 16) + (2n + 10) = 180             <em>combine like terms</em>

(5n + 2n) + (16 + 10) = 180

7n + 26 = 180            <em>subtract 26 from both sides</em>

7n + 26 - 26 = 180 - 26

7n = 154         <em>divide both sides by 7</em>

7n/7 = 154/7

n = 22

Insert the value of n into expressions that specify angle measures:

m∠EFG = 5n + 16 → m∠EFG = 5(22) + 16 = 110 + 16 = 126°

m∠GFH = 2n + 10 → m∠GFH = 2(22) + 10 = 44 + 10 = 54°

A dilation is a transformation whose preimage and image are _____
Paha777 [63]

Answer:

proportional/noncongruant

Step-by-step explanation:

This is because when you dilate an image it changes size and that means the image is not congruent to the preimage but they will stay proportional since they keep the same shape.
