The value of x from the given diagram is 16.6
<h3>Secant-secant theorem</h3>
In order to determine the value of x from the given figure, we will use the secant-secant theorem shown by the equation.
(6 +12) * 6 = (5 + x) * 5
Expand
36+72 = 25 + 5x
108 = 25 + 5x
5x = 108 - 25
5x = 83
x = 83/5
x = 16.6
Hence the value of x from the given diagram is 16.6
