Answer:

BC=53.68

Step-by-step explanation:

Use tangent since you are finding the opposite side and given the adjacent side.

tan(54)=BC/39

BC=53.68

Answer:

C

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan54° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{39}[/tex] ( multiply both sides by 39 )

39 × tan54° = BC, then

BC ≈ 53.68 ( to 2 dec. places ) → C
