I think it’s B. since it’s on the adjacent & hypotenuse side it makes it cosine, and the correct way to set it up is B i believe. hopefully i’m not wrong because it could also be D

Step-by-step explanation:

$let \: angle \: be \: \alpha \\ \tan( \alpha ) = \frac{p}{b} \\ \tan(69.9) = \frac{9.7}{bc} \\ bc = \frac{9.7}{2.73} \\ bc = 3.55 \\ by \: using \: pythagorean \: theorem \\ ab = \sqrt{ {9.7}^{2} } + {2.73}^{2} \\ ab = 10.07$
