Solution

Part a

For this case we can solve the value of x with the following proportion rule:

[tex]\frac{x}{12}=\frac{20}{16}[/tex][tex]x=12\cdot\frac{20}{16}=15[/tex]

Part b

We can do the following:

[tex]\frac{x}{6}=\frac{20}{8}[/tex]

And solving we got:

[tex]x=6\cdot\frac{20}{8}=15[/tex]

Part c

For this case we can see that both answers are equal since we satisfy the proportional rule between equivalent sides of the similar triangles
