• Equality Properties

Trigonometry

• sin∅ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define variables

∅ = 39°

opposite leg = 9

hypotenuse = x

Step 2: Solve for x

1. Substitute:                              sin39° = 9/x
2. Multiply x on both sides:       xsin39° = 9
3. Isolate x:                                 x = 9/sin39°
4. Evaluate:                                 x = 14.3011
5. Round:                                    x ≈ 14.30
