Answer:

10.5

Step-by-step explanation:

tan(55°)=15/b

b=15/tan(55°)

=10.5

Answer:

AC ≈ 10.5

Step-by-step explanation:

tan55° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{b}[/tex]

Multiply both sides by b

b × tan55° = 15 ( divide both sides by tan55° )

b = [tex]\frac{15}{tan55}[/tex] ≈ 10.5

Hence b = AC ≈ 10.5 ( to the nearest tenth )
