Help please thank you lol

DE=3 cm

Step-by-step explanation:

From the information we know, we can tell that triangle ABC is a scale factor of 2 from triangle DEF, because 10/5=2.

Side DE would be proportional to side AB.

Side AB is 6, so we would have to divide that by 2, because of our scale factor.

6/2=3.

Hope this helped! Have a good rest of your day!

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
