Question

Quadrilateral CDEF is similar to quadrilateral GHL. Find the measure of side IJ. Round your answer to the nearest tenth. 39 19 60.2

Answer 1

Let:

$\begin{gathered} kFC=JG \\ where \\ k=scale_{\text{ }}factor \\ k19=60.2 \\ so\colon \\ k=\frac{60.2}{19} \\ k=\frac{301}{95} \end{gathered}$

Therefore:

$\begin{gathered} kFE=IJ \\ \frac{301}{95}\cdot39=IJ \\ IJ=123.6 \end{gathered}$
