Question

आकृती काढून प्रश्नाचे उत्तर लिहा.

जर X-Y-Z आणि l(XZ) = 3${\displaystyle \sqrt{7}}$, l(XY) = ${\displaystyle \sqrt{7}}$, तर l(YZ) = ?

Answer 1

दिले आहे, l(XZ) = 3${\displaystyle \sqrt{7}}$, l(XY) = ${\displaystyle \sqrt{7}}$

आता, l(XZ) = l(XY) + l(YZ)      ...(X-Y- Z)

∴ l(YZ) = l(XZ) − l(XY)

∴ l(YZ) = ${\displaystyle 3\sqrt{7}-\sqrt{7}}$

∴ l(YZ) = ${\displaystyle 2\sqrt{7}}$
