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 <em>acute angel = opposite side/ hypotenuse side</em>
So that, in triangle VWX:
+) <em>sin ∠W = XV / WV </em>
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
