Question

Using soh cah toa find length of WX and round to the nearest tenth of a foot?

Answer 1

The answer is 14 feet listen to the guy above me

Answer 2

The length WX is about 14 feet.

Explanation:

This problem involves finding the adjacent side to a known acute angle in a right-angle triangle, therefore, the trigonometric function that we use is that of the tangent of the angle:

`tan(\theta)=(opposite)/(adjacent) \\tan(31^o)=(8.4)/(x)\\x=(8.4)/(tan(31^o))\\x=13.9799\\x \approx 14`

Therefore, the length WX is about 14 feet.
