1. B

   Step-by-step explanation:

   Using the cosine ratio in the right triangle

   cos54° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{39}{AB}[/tex] ( multiply both sides by AB )

   AB × cos54° = 39 ( divide both sides by cos54° )

   AB = [tex]\frac{39}{cos54}[/tex] ≈ 66.35 → B
