How do i find the altitude of an equilateral triangle with side lengths of 8 in.?

Question

anonymous · Answer

altitude bisects the side of the equilateral triangle so the triangle would be split into 2 triangles with side measures 4 and 8. the triange angle measure would be 90 30 60 so the altitude is 4$$4\sqrt{3}$$

root3                      root3
altitude = ---------- x side = ------- x 8 = 4 root3

if the angles of a triangle are 30 60 and 90 then the hypotenuse is 2x the short side and the long side = short side root 3 which in this case is $$4\sqrt{3}$$
