Question

In the problem below -- do you use the leg rule or the altitude rule to solve?EHEF = 10HF = XGF = 5Find x

Answer 1

We need to identify the correct rule to solve this problem.

Notice that triangles EGF and GHF are similar:

So, we have:

`\begin{gathered} (EF)/(GF)=(GF)/(HF) \\ \\ (10)/(5)=(5)/(x) \end{gathered}`

Now, using the leg rule, we obtain:
