What is true about the dilation?

it has a scale factor between zero and one and is a reduction.
it has a scale factor greater than one and is a reduction.
it has a scale factor between zero and one and is an enlargement.
it has a scale factor greater than one and is an enlargement.

Answer with explanation:

When the size of Preimage is greater than size of Image than dilation factor will be less than 1 and greater than zero.

And, when Size of preimage is greater than Size of Image than dilation factor will be greater than 1.

In the given diagram

Size of Preimage > Size of Image

Dilation Factor=0 <Dilation factor <1

Option A: It has a scale factor between zero and one and is a reduction.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
