Answer:

BC = 205.8 feet

Step-by-step explanation:

We only have one side, DB, so we have to use the given angles rather than the Pythagorean theorem.

Answer:

BC ≈ 205.8 ft

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BD}{BC}[/tex] = [tex]\frac{67}{BC}[/tex] ( multiply both sides by BC )

BC × cos71° = 67 ( divide both sides by cos71° )

BC = [tex]\frac{67}{cos71}[/tex] ≈ 205.8 ft ( to the nearest tenth )
