3. The triangle will be dilated by a scale factor of 2.5.
(a) What is the length of each of the sides after the dilation?
(b) Draw the new image and label it .

Answer 1

Do you still need help with this? If so just say if you do in the comments and I can probably help.

Explanation:

Answer 2

Part a) The length of each of the sides after the dilation is

`A'B'=30\ units`

`B'C'=25\ units`

`A'C'=35\ units`

Part b) The graph in the attached figure

Explanation:

Part a) What is the length of each of the sides after the dilation?

In this problem we have that the scale factor is 2.5

The scale factor is greater than 1

so

The dilation is an enlargement

To find the length of each of the sides after the dilation, multiply the original length by the scale factor

so

`A'B'=AB*2.5=12*2.5=30\ units`

`B'C'=BC*2.5=10*2.5=25\ units`

`A'C'=AC*2.5=14*2.5=35\ units`

Part b) Draw the new image and label it

using a graphing tool
