Equilateral triangles are also isosceles, and if a sgmt from a vertex is perpendicular to the base, then the base is bisected. Refer to picture. Then we can use pythagorean's thm on the right triangle with leg 4 and hyp 8 to solve for TX.

4² + TX² = 8²
TX² = 64 - 16
TX² = 48
TX = sqrt(16*3)
TX = 4sqrt(3)
