Answer:
the answer will be 8cm
Step-by-step explanation:
it is because according to the theorum of tangents of circle the two tangents drawn from a common point has the same length
now, the tangent PC has its common point both with the tangents AP and CD so it is a sum of length of both the tangent
so, PC=5+3=8cm
