Find EF, to the nearest tenth

24.0

Step-by-step explanation:

It is given that in triangle DEF, DE=15 and m∠F=32°

In triangle DEF, using the trigonometry, we have

Substituting the given values, we have

⇒

⇒

⇒

Thus, the value pf EF is 24.0

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
