Answer: 1/3
Step-by-step explanation:
We know that after dilation with scale factor k the coordinates of pre-image (x,y) map to (kx,ky) of the image.
From the given graph, the coordinate of A =(9,4) and the coordinate of A' (3,2)
Then 
and 
Therefore, the scale factor of the dilation is 1/3.
If you repost with a question or snapshot, I would be capable of answering it.
Answer:
y = 9.84 mm
Step-by-step explanation:
<h2>Sine rule:</h2>
Law of sine:
a = y
A = 31°
b = 17 mm
B = 117°
The red figure is smaller so it is a reduction.
To find the scale factor divide the length of the smaller shape by the length of the larger shape:
9/15 this can be reduced to 3/5
