Answer:

PC = 12 units

AP = 10 units

Step-by-step explanation:

  • The centroid of a triangle is the intersection of the three medians of the triangle
  • Each median connecting a vertex with the midpoint of the opposite side
  • The centroid divides each median into two parts, which are always in the ratio 2: 1 from the vertex

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
