Question

I was doing my homework and got confused on this question.

Answer 1

We will determine the length of the segment DF as follows:

*We have that the triangles are similar, and therefore the following is true:

$\frac{2}{1.34}=\frac{4}{DF}$

Now, we solve for DF:

$\Rightarrow DF=\frac{1.34\cdot4}{2}\Rightarrow DF=2.68$

From this, we have that the length of the segment DF equals 2.68 units.
