The geometric mean between 4 and 8 is 6. When an altitude is drawn to the hypotenuse of a right triangle, there are 3 similar triangles formed. The hypotenuse of a 30-60-90 triangle is twice as long as the shortest side. The Pythagorean theorem says that in a right triangle, the hypotenuse is equal to the sum of the two legs.
