SI imi triangles. 16. JK 17 ST J X K 4 6 L R Р 12 M P TTTT 20. DB

Sagot :

16.

In the given triangles,

[tex]\begin{gathered} \angle JLK=\angle PLM\text{ (Vertically Opposite Angle)} \\ \angle LJK=\angle LPM\text{ (Given)} \end{gathered}[/tex]

Hence form AA critesion,

[tex]\Delta JLK\approx\Delta PLM[/tex]

From the property of similar triangles,

[tex]\begin{gathered} \frac{JK}{PM}=\frac{JL}{PL} \\ \Rightarrow\frac{x}{12}=\frac{4}{6} \\ \Rightarrow x=8 \end{gathered}[/tex]

Thus, the requried value of JK is 8.
