x = 11.9

the trigonometry ratio to use is cos

Step-by-step explanation:

The triangle is a right angled triangle. So we would apply the trigonometry ratio SOHCAHTOA

The given angle is 32 degrees

opposite = the side opposite the angle 32 degrees

adjacent = base = x

hypotenuse = 14

Since we have been given the value of hypotenuse and we want to find the adjacent, we would apply cosine ratio (CAH)

Cos 32° = adjacent/hypotenuse

cos 32° = x/14

14(cos 32°) = x

x = 14(0.8480)

x = 11.872

To the nearest tenth, x = 11.9

Hence, the trigonometry ratio to use is cos
