Trigonometry

• [Right Triangles Only] SOHCAHTOA
• [Right Triangles Only] sinθ = opposite over hypotenuse

Explanation:

Step 1: Identify Variables

Angle θ = x°

Opposite Leg = 3

Hypotenuse = 8

Step 2: Find x°

1. Substitute [Sine]: sinx° = 3/8
2. Inverse trig: x° = sin⁻¹(3/8)
3. Evaluate: x = 22.0243°
4. Round: x ≈ 22.0°
