Answer:
b ≈ 35 yd
Step-by-step explanation:
using the tangent ratio in the right triangle
tan41° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{30}{b}[/tex] ( multiply both sides by b )
b × tan41° = 30 ( divide both sides by tan41° )
b = [tex]\frac{30}{tan41}[/tex] ≈ 35 yd ( to the nearest whole number )
