Answer:

WV = 169.591 feet

Step-by-step explanation:

As VWX has ∠X equal to 90°, so that it is the right triangle.

In the right triangle, there is a formula as following:

    sin acute angel = opposite side/ hypotenuse side

So that, in triangle VWX:

+) sin ∠W = XV / WV

as ∠W =20° and XV is equal to 58 feet, replace it into the formula above, we have:

sin ∠W = sin 20° = 58/ WV

=> WV = 58/ (sin 20°)

sin 20° ≈ 0.342

=> WV ≈ 58/ 0.342 = 169.591 feet
