Answer:

x ≈ 13.8

Step-by-step explanation:

using the cosine ratio in the right triangle

cos37° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )

x × cos37° = 11 ( divide both sides by cos37° )

x = [tex]\frac{11}{cos37}[/tex] ≈ 13.8 ( to the nearest tenth )
