Step-by-step explanation:
Hi friend ✋
side = 8cm
draw a equilateral triangle ABC and draw it it's altitude AD on BC
however the altitude divides the side into two then DC = BD = 4cm
by applying Pythagoras theorem in∆ ADC
AC² = DC² + AD²
then
AD² = 8² - 4²
AD² = 64 -16
AD = √(48)
AD = 4√3cm
hope it helps
