Trigonometry

• [Right Triangles Only] SOHCAHTOA
• [Right Triangles Only] tanθ = opposite over adjacent

Explanation:

Step 1: Identify Variables

Angle θ = x°

Opposite Leg = 10

Hypotenuse = 21

Step 2: Solve for x

1. Substitute [tangent]: tanx° = 10/21
2. Inverse trig: x° = tan⁻¹(10/21)
3. Evaluate: x = 25.4633°
4. Round: x ≈ 25.5°
