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)
