To find that out, we must find out how much larger <DEF is than <ABC
So we take the sides DE and divide it by AB
4.5/3=1.5
That means <DEF is 1.5 times larger than <ABC
So now, we take BC, and multiply it by 1.5
2 x 1.5 = 3
So EF=3
Hope this helps!

Answer: A phase shift horizontal translation to the right.
Step-by-step explanation:
A periodic function that does not start at the sinusoidal axis or at a maximum or a minimum has been shifted horizontally. This horizontal movement allows for different starting points since a cosine wave does not have a beginning or an end.
In this question, the sinusoidal wave is a cosine function of F(x) = cos x.
So to change the parent cosine function to the cosine function above, A phase shift horizontal translation to the right must have been done.
