Question

I dont understand this​

Answer 1

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)
