10/x  =  x/6  ?

60 = x^2

x = sqrt 60     Is that right? cheeky

The measure of the altitude drawn from the vertex of the right angle of a right triangle to its hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.

 

Knowing that  x = sqrt( 10 * 6 ) = 7.745966692
