Answer:

x = 13.8

Step-by-step explanation:

Reference angle =
\theta = 37

Hypotenuse length = x

Adjacent length = 11

To find the value of x, we would apply the following trigonometric ratio (CAH):


Cos(\theta) = (Adjacent)/(Hypotenuse)

Plug in the values


Cos(37) = (11)/(x)

Cross multiply


x * Cos(37) = 11

Divide both sides by Cos(37)


x = (11)/(Cos(37))


x = 13.8 (nearest tenth)
