Answer:
BC ≈ 5.87
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{7}{BC}[/tex]
Multiply both sides by BC
BC × tan50° = 7 ( divide both sides by tan50° )
BC = [tex]\frac{7}{tan50}[/tex] ≈ 5.87 ( to the nearest hundredth )
