  • [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

  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
