Which transformation maps the large triangle onto the
small triangle?
dilation
reflection
Orotation
translation

dilation

Step-by-step explanation:

dilation; to dilate means to compress, so when an original triangle dilates, it means it gets smaller and we can speak in reference of a large triangle to a smaller triangle.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
