Cum pot afla laturile unui triunghi echilateral ,daca inaltimea este 2√3?

Răspuns :

[tex]Intr-un~triunghi~echilateral~de~latula~l,~lungimea~ \\ \\ inaltimii~este~data~de~formula:~ \boxed{ h=\frac{l \sqrt{3}}{2} }. \\ \\ Deci~ \frac{l\sqrt{3}}{2}=2 \sqrt{3} \Rightarrow l=4~(cm). [/tex]

[tex]h= \frac{l \sqrt{3} }{2} =\ \textgreater \ 2\sqrt{3} = \frac{l \sqrt{3} }{2} =\ \textgreater \ \\ l = \frac{2*2 \sqrt{3} }{ \sqrt{3} } =4 [/tex]
