Answer:
B) 6.9 cm
Step-by-step explanation:
The remaining angle is the smallest, 180° -48° -97° = 35°. The shortest side is opposite this angle. The Law of Sines tells you its length is ...
short side = (longest side)·(sin(smallest angle)/sin(largest angle))
= (12 cm)sin(35°)/sin(97°) ≈ 6.9 cm
The shortest side is about 6.9 cm.
