Answer:
GD = 4
AD = 12
CG = 14
GE = 10
BE = 15
Explanation:
Because G is the centroid, then the following are correct
CG : GF = 2 : 1
AG : GD = 2 : 1
GE : BG = 2 : 1
So to find
GD, given AG = 8, we have:
8/GD = 2/1
GD = 8/2 = 4
AD = AG + GD
= 8 + 4
= 12
CG/GF = 2/1
CG/7 = 2/1
CG = 14
GE/BG = 2/1
GE/5 = 2/1
GE = 10
BE = GE + BG
= 10 + 5
= 15
Answer:
subtracting 8 from both sides of the equation
Step-by-step explanation:
5/10 miles left
Because 9/10 minus 4/10 is 5/10
Answer:
AD : DC is 2:3
Step-by-step explanation:
The parameters given are;
Point B ∈ AC
AB : BC = 2:1
Point D ∈ AB
AD : DB = 3:2
Therefore, whereby we sum the ratios, we have;
For AC
AB = 2/(2+1)×AC = 2/3×AC
BC = 1/3×AC
For AB
AD = 3/(3+2)×AB = 3/5×AB
DB = 2/5×AB
We are required to find AD:DC
Given that AD = 3/5×AB and AB = 2/3×AC
We have;
AD = 3/5×2/3×AC = 6/15 AC
DC = DB + BC = 2/5×AB + 1/3×AC = 2/5×2/3×AC + 1/3×AC = 4/15×AC + 1/3×AC
DC = 3/5×AC
AD : DC = 6/15 AC : 3/5×AC = 2:3.
