How do I find this review question? I’m confused need help

Answer 1

In order to solve this, we can use the trigonometric ratio of the cosine, which is given by the following expression:

`\cos \theta=(ac)/(h)`

Where ac is the adjacent leg to the angle θ and h is the length of the hypotenuse. By replacing 37° for θ, 17.3 for ac and x for h, we get:

`\cos 37=(17.3)/(x)`

From this expression, we can solve for x to get:

`x=(17.3)/(\cos 37)\approx21.7`

Then, x = 21.7
