In the diagram below, PA= 
4, AB=2, and PC=3. Find
the length of PD.
                                             
                                          
                                          
                                        
											 
											Answer:
PD = 8
Step-by-step explanation:
PC x PD = PA x PB
3 x PD = 4 x (4 + 2)
3PD = 24
PD = 8
