Question

In the figure below, triangle DBA is similar to triangle ECA. Ramon wants to know the distance across the lake. 982 320 m 40 m

Answer 1

Let's use thales theorem:

`\begin{gathered} (320)/(482)=(40)/(d) \\ \end{gathered}`

Solving for d:

`\begin{gathered} d=(482*40)/(320) \\ d=60.25m \end{gathered}`
