Answer:
b ≈ 43 yd
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan28° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{23}{b}[/tex] ( multiply both sides by b )
b × tan28° = 23 ( divide both sides by tan28° )
b = [tex]\frac{23}{tan28}[/tex] ≈ 43 yd ( to the nearest whole number )
