Explanation:

the formula for the height in a right-angled triangle is

h = sqrt(p×q)

p and q being the segments of the Hypotenuse left and right from the point, where the height intersects with the Hypotenuse.

so, in our case

12 = sqrt(16×(x-16))

let's square this to eliminate the square root :

144 = 16×(x - 16) = 16x - 256

400 = 16x

x = 25
