Question

Need help with a equation

Answer 1

26.6

RS is similar to NM, and TP is similar to OL.

If they're similar they have to be proportional. So:

`\begin{gathered} (NM)/(RS)=\text{ }(OL)/(TP)\text{ } \\ (7)/(RS)=(5)/(19) \\ RS\text{ = }(19\left(7\right))/(5) \\ RS=\text{ 133/5} \\ RS=26.6 \end{gathered}`
