Question

I narrowly answered the first question on my homework but for some reason EF really confuses me.

Answer 1

Part 1

For this case we can find DF with the following proportion formula:

`(AC)/(AB)=(DF)/(DE)`

And replacing we got:

`(4)/(2)=(DF)/(1.34),DF=2.68`

Part 2

`(BC)/(AB)=(EF)/(DE)`

And solving for EF we got:

`EF=1.34\cdot(3)/(2)=2.01`
