Question

Am I doing this correct? Given: ΔABC ≅ ΔEFD

What is the length of rounded to the nearest tenth?

2.8
3.4
4.1
6.1

Answer 1

Is the correct answer 3.4

Answer 2

Can anyone please tell me if I am correct?

Answer 3

What are we finding the length of?

Answer 4

Sorry it is FE and it has a line over it

Answer 5

Yeah. So you would use the distance formula carrect.

Answer 6

yes I think

Answer 7

So \[d= \sqrt{(x_{2}-x_{1})^2+(y_{2}-y _{1})^2}\]

Answer 8

So since we have FE is congruent to BA
So (x1,y1)=(2,4)
And
(x2,y2)=(0,2)
\[d \sqrt{0-2)^2+(2-4)^2}\]
\[d=\sqrt{(-2)^2+(-2)^2}\]
\[d=\sqrt{4+4}\]
\[d=\sqrt{8}\]
\[d=2.828427....\]

Answer 9

thank you soo much :)

Answer 10

No problem.
