Find the exact value of x.
Similar triangles: 10 : x = x : 6
10/x = x/6 ?
60 = x^2
x = sqrt 60 Is that right?
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
