• sin∅ = opposite over hypotenuse

Explanation:

Step 1: Define

∠ = 24°

opposite = 14

hypotenuse = x

Step 2: Find x

1. Set up equation: sin24° = 14/x
2. Multiply both sides by x: xsin24° = 14
3. Isolate x: x = 14/sin24°
4. Evaluate: x = 34.4203
5. Round: x ≈ 34.4

And we have our final answer!
