Answer:
SAS
Explanation:
Eliminate the choices.
Not SSS, as you are only given 2 out of 3 side lengths, and you need an angle measure to find the third length
Not AA, since we cant be sure
But seeing as there is one angle that corresponds for both triangles and are in-between two sides, it would be SAS (its not good to pressume, but thats all you can do )
