Answer:

8.944

Step-by-step explanation:

To find the missing Length, Use Pythagorean Theorem!

$a^2+b^2=c^2$

$4^2+8^2=c^2$

$16+64=c^2$

$80=c^2$

$\sqrt{80} =8.944$

attashe74 [19]

Answer:

(2,-1)

Multiply everything by 1/3:

6*1/3=2

-3*1/3=-1

This makes it smaller, so you know what the dilation is.

Hey there! :D

The midpoint and the outside line are symmetrical to eachother, 2(BF)= AE

Two midpoint segments equals one AE segment.

So, use the representation above and plug in the numbers.

2(23)= 5x -4

56= 5x-4

Add 4 to both sides.

60=5x

Divide by the 5.

x=12

I hope this helps!
