• [Right Triangles Only] tan∅ = opposite over adjacent

Explanation:

Step 1: Identify Variables

Angle = 35°

Opposite Leg = 3

Adjacent Leg = x

Step 2: Solve for x

1. Substitute [tangent]: tan35° = 3/x
2. Multiply x: xtan35° = 3
3. Isolate x: x = 3/tan35°
4. Evaluate: x = 4.28444
5. Round: x ≈ 4.3
