Answer:

x ≈ 25.1

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos64° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )

x × cos64° = 11 ( divide both sides by cos64° )

x = [tex]\frac{11}{cos64}[/tex] ≈ 25.1 (  to the nearest tenth )
