  • [Right Triangles Only] SOHCAHTOA
  • [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
