General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS

Trigonometry

• sin∅ = opposite over hypotenuse

Step-by-step 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!
