Question
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
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
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
