Question

Triangle BCD is similar to triangle EFG. Find the measure of side EF. Round your answer to the nearest tenth. Figures are not drawn to scale. E G D9 X 43 19 F B

Answer 1

The ratio of the corresponding sides of two similar triangles is equal. Since traingles BCD and EFG are similar, we can write

`\begin{gathered} (BC)/(EF)=(CD)/(FG) \\ (19)/(x)=(9)/(43) \\ x=19*(43)/(9) \\ x=90.8 \end{gathered}`
