Answer:
51+x-5+y-6=180
x+y=180-51+5+6
X+y=140
Answer x=77 y=63
(those 2 lines with the arrows are perpendicular so their angles are the same 72° and (x-5)=77-5= 72°)
Answer:
The scale factor is 1.
Step-by-step explanation:
Let k be the scale factor of a dilation of triangle ABC to form the image triangle A'B'C'.
The dilation is a magnification if

In this case, the preimage will be similar to the image triangle.
If

the dilation is a reduction. The image and pre-image will still be similar.
But if

the image is the same as the preimage.
We say the pre-image is congruent to the image triangle.
