The two triangles above are similar
(The triangle to the right show the numbers 6,12, and x. The triangle to the left has the numbers 20,16 and 8.)
A. Find x using the ratios of the sides 12 cm and 6 cm: x/20=12/16
B. Find x using the ratios of the sides 6 cm and 8 cm
C. Explain why the answers to A and B should be the same.
I don’t understand this question and any help would be very appreciated.

We can not see your drawing
if a,b,c is similar to A, B, C then
a/b = A/B
a/c= A/C
b/c = B/C
etc, etc, etc

I would assume that you wrote the sides in the proper correspondence, that is if
6:12:x = 20,16,8
then the angle opposite 6 would be equal to the angle opposite 20 etc
then 6/20 = 12/16, which is not the case

relist the sides in their corrct sequence
