Help please on this question

Answer 1

To solve this problem, I'll use proportions

`\begin{gathered} \text{ }\frac{RS}{RV\text{ + VT}}\text{ = }(RV)/(RS) \\ \text{ RS(RS) = RV(RV + VT)} \end{gathered}`

Substitution

`\begin{gathered} \text{ RS}^2\text{ = 4.1(4.1+ 10.2)} \\ RS^2\text{ = 4.1(14.3)} \\ RS^2\text{ = 58.63} \\ RS\text{ = 7.66} \end{gathered}`

Rounding to the nearsert tenth

This is the result;

RS = 7.7
