In triangle ACE, P is the centroid, PF = 6 , and AD = 15 15. Find the measures of PC and AP. Enter your answers as numbers.

Answer:
PC = 12 units
AP = 10 units
Step-by-step explanation:
In ΔACE
∵ P is the centroid of it
∴ P divides CF the ratio 2: 1 from C
∴ PC = 2 PF
∵ PF = 6 units
∴ PC = 2(6)
∴ PC = 12 units
∵ P divides AD at the ratio 2: 1 from A
→ That means AD = 2 + 1 = 3 parts, and AP = [tex]\frac{2}{3}[/tex] AD
∴ AP = [tex]\frac{2}{3}[/tex] AD
∵ AD = 15 units
∴ AP = AP = [tex]\frac{2}{3}[/tex] (15)
∴ AP = 10 units
