Answer 1

cos x= adjacent/hypotenus

cos x= 18/22

cos x=0.8182

x=35.09⁰

Answer 2

`\cos(x) \approx 0.82`

Explanation:

Cosine is defined as:

adjacent / hypotenuse.

We can determine that 18 is the side adjacent to x, and that 22 is the triangle's hypotenuse.

Putting these values into the definition of cosine:

`\cos(x) = \frac{\text{adj}}{\text{hyp}}`

`\cos(x) = (18)/(22)`

`\cos(x) \approx 0.82`
