Question

Ajutor!!!! Un triunghi echilateral are latura l=10 cm. Calculati înălțimea si aria triunghiului..Dau coroană!!

Answer 1

$\displaystyle \mathtt{h=\frac{\sqrt3}{2} \cdot l=5\sqrt3cm} \\ \\ \mathtt{A=\frac{\sqrt3}{2} \cdot l^2=50\sqrt3cm^3}$

Answer 2

h=lrad 3/2
h=10rad3/2
h=5rad 3
A=L^2rad3/4
A=10^2rad3/4
A=100rad3/4
A=25rad3
