  A, C

Step-by-step explanation:

The given ratio can be reduced by removing a factor of 2 from each element.

  8 : 6 = 4 : 3 . . . . matches A

It can be put in other forms by multiplying each element by the same factor. Using a factor of 2 on the original ratio values, we get ...

  8 : 6 = 16 : 12 . . matches C

Any ratio that doesn't reduce to the integer ratio 4 : 3 is not equivalent. The ratio with elements reversed (3:4) is not equivalent.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
