Question

If 6-foot-tall Madeleine casts an 108-inch shadow, how tall is her friend if, at the time, his shadow is 1.5 feet shorter than hers.thank you ! :)

Answer 1

We would use similar triangle relations to solve this;

We have the triangles set up , thus;

`\begin{gathered} (x)/(6)=(7.5)/(9) \\ x=5\text{ ft} \end{gathered}`

Therefore, her friend is 5 feet tall.
