Respuesta :

Answer:

Step-by-step explanation:

Cos Q = adj/hyp

Cos 66 = x/13

x = 13 × cos 66

x = 13 × 0.4067

x = 5.287

x = 5.3

Answer:

x ≈ 5.3

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos66° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{13}[/tex]

Multiply both sides by 13

13 × cos66° = x, thus

x ≈ 5.3 ( to the nearest tenth )
