Answer:

Option A) 4

Step-by-step explanation:

we know that

Applying the Intersecting Secant-Tangent Theorem

[tex]PA^{2}=(BE+PE)( PE)[/tex]

substitute the given values

[tex]6^{2}=(5+PE)( PE)\\ \\36=PE^{2}+5PE\\ \\PE^{2}+5PE-36=0[/tex]

Solve the quadratic equation by graphing

The solution is PE=4 units

see the attached figure
