What is the length of the altitude of an equilateral
triangle whose side has a length of 8?

Respuesta :

Using Pythagorean theory the square of the hypotenuse minus the square of the base equals the square of the other side (altitude).

So 8*8=64, 4*4=16, 64–16=48 so the altitude of the triangle is the √48.
