Chapter 1, Problem 25RP

To determine

To calculate: The value of WX.

Answer to Problem 25RP

The value of $WX$ is $15$ .

Explanation of Solution

Given information: Here, we have given that WX = $25$ and Ratio of WX to XY is $3:2$ .

Calculation: From the given figure, we can determine that WY = WX + XY.

Let the common measurement be $x$ .

  $\therefore$ WX = $3x$ and XY = $2x$

As, WY = WX + XY

  $\therefore$ $25=3x+2x$

  $\Rightarrow 25=5x$

  $\Rightarrow x=\frac{25}{5}$

  $\Rightarrow x=5$

  $\begin{array}{l}\Rightarrow WX=3(5)\\ \therefore WX=15\end{array}$
