The value of x according to the triangular altitude theorem is 5 units.
Triangular altitude theorem
According to the triangular altitude theorem, the expression below is true;
AD/BD = BD/DC
Substitute the given parameters
x/10 = 10/4x
Cross multiply
4x(x) = 10(10)
4x^2 = 100
x^2 = 100/4
x^2 = 25
x = 5
Hence the value of x according to the triangular altitude theorem is 5 units.
