Triangle DEF is a dilation of triangle ABC with scale factor 2. In triangle ABC, the largest angle measures 82∘. What is the lar
uysha [10]

Answer:

Option 2) 82°

Step-by-step explanation:

The dilation means the enlargement of the figure or reduction in the size of the figure.

If the scale factor is greater than 1, its an enlargement

If the scale factor is smaller than 1, it is a reduction.

But what ever be the case,

the triangles always remain similar.

Hence the size of the sides changes,

But the size of the angles always remains the same.

Now the largest angle of triangle ABC is 82°.

Hence the largest angle of the triangle DEF shall be 82°.

Second option 82° is the right answer.

a circular dog pen has a circumference of 78.5 feet. approximate by 3.14 and estimate how many hunting dogs could be safely kept
olasank [31]

Answer:

  8

Step-by-step explanation:

To solve this problem, we need to find the area of the pen, then divide that by the area required by each dog.

__

The relationship between circumference and radius is ...

  C = 2πr

Solving for r gives ...

  r = C/(2π)

The relationship between radius and area of a circle is ...

  A = πr²

Substituting for r from above gives ...

  A = π(C/(2π))² = C²/(4π)

Filling in the given numbers, we find the area of the pen to be ...

  A = (78.5 ft)²/(4·3.14) = 490.625 ft²

__

Dividing the pen area by the area per dog gives the number of dogs the pen can hold:

  (490.625 ft²)/(60 ft²/dog) ≈ 8.18 dogs

The pen can safely keep 8 dogs.
