Question

In the following figure, the similarity ratio of regular hexagon P to regular hexagon T is 4/5 and the similarity ratio of regular hexagon R to T is 2/5. What is the difference of n and m?

Answer 1

6 = 2/5(n-4)
15 = n-4
n = 19

m+12 = 4/5(n-4)
m+12 = 4/5(15)
m+12 =12
m=0
difference between m and n = 19-0 = 19
