Answer:
0.87
Step-by-step explanation:
Answer:

Step-by-step explanation:
So we have the equation:

Subtract 7 from both sides:

Divide both sides by 3:

So, the value of w is 4.
And we're done!
180-65=115°
that's the answer

Answer:

Step-by-step explanation:
A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.
When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".
When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".
In this case you know that the triangle ABC was dilated by this scale factor:

With the origin as the center of dilation.
Since:

It is a Reduction.
You can identify that the vertices of the triangle ABC are:

So you need to multiply the coordinates of each vertex of the triangle ABC by
, in order to get the coordinates of the triangle A'B'C. Then, you get:
