Question

Are the two triangles in the figure Similar? Justify the answer.what is the distance d across the lake?

Answer 1

Two triangles are Similar if the only difference is size (and possibly the need to turn or flip one around). Therefore would be answer B.

Find the ratio

`\begin{gathered} (80)/(30)=(d)/(180) \\ d=180\cdot(80)/(30) \\ d=480\text{ ft} \end{gathered}`

The distance would be 480 ft
