- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Explanation:
Step 1: Identify Variables
Angle Measure = 60°
Adjacent Leg = 9
Opposite Leg = x
Step 2: Solve for x
- Substitute [tangent]: tan60° = x/9
- Isolate x: 9tan60° = x
- Rewrite: x = 9tan60°
- Evaluate: x = 15.5885
- Round: x ≈ 15.6
