Question

Calculati lungimea inaltimii unui triunghi echilateral cu latura de lungime : a) 8 cm b) 6√3 cm c) 15√2 d) 8√3 pe 3 cm . Dau funda

Answer 1

h=L√3/2
a) h=8√3/2=4√3
b) h=6√3*√3/2=9
c) h=15√2*√3/2=15√6/2
d) h=(8√3/3 * √3)/2=4

Answer 2

[$[tex]h= \frac{l \sqrt{3} }{2} \\ a)h =\frac{8 \sqrt{3} }{2}=4 \sqrt{3} \\ b)h= \frac{6 \sqrt{3}* \sqrt{3} }{2}=3 \sqrt{9} \\ c)h= \frac{15 \sqrt{2}* \sqrt{3} }{2}= \frac{15 \sqrt{6} }{2} \\ d) \frac{ \frac{8 \sqrt{3} }{3}*\sqrt{3} }{2} = \frac{ \frac{8 \sqrt{9} }{3} }{2} = \frac{ \frac{8*3}{3} }{2}= \frac{8}{2}=4$
