Answer:

x = 13.8

Explanation:

Reference angle = [tex] \theta = 37 [/tex]

Hypotenuse length = x

Adjacent length = 11

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

[tex] Cos(\theta) = \frac{Adjacent}{Hypotenuse} [/tex]

Plug in the values

[tex] Cos(37) = \frac{11}{x} [/tex]

Cross multiply

[tex] x \times Cos(37) = 11 [/tex]

Divide both sides by Cos(37)

[tex] x = \frac{11}{Cos(37)} [/tex]

[tex] x = 13.8 [/tex] (nearest tenth)
