Answer:

The value of x is [tex]2\ units[/tex]

Step-by-step explanation:

we know that

Applying the  tangent-secant theorem

[tex]AP^{2}=PB*PC[/tex]

substitute the values and solve for x

[tex]\sqrt{10}^{2}=x*(x+3)[/tex]

[tex]10=x^{2}+3x[/tex]

[tex]x^{2}+3x-10=0[/tex]

using a graphing tool

to solve the quadratic equation

The solution is [tex]x=2\ units[/tex]

see the attached figure
