• [Right Triangles Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

Angle Measure = 60°

Adjacent Leg = 9

Opposite Leg = x

Step 2: Solve for x

1. Substitute [tangent]:                    tan60° = x/9
2. Isolate x:                                       9tan60° = x
3. Rewrite:                                        x = 9tan60°
4. Evaluate:                                       x = 15.5885
5. Round:                                          x ≈ 15.6
