x ≈ 15.0 ft

General Formulas and Concepts:

Pre-Algebra

  • Equality Properties

Trigonometry

  • tan∅ = opposite over adjacent

Step-by-step explanation:

Step 1: Define

Angle = 28°

Opposite leg of angle = 8 ft

Adjacent leg of angle = x ft

Step 2: Find x

  1. Substitute:                                        tan28° = 8/x
  2. Multiply x on both sides:                 xtan28° = 8
  3. Divide tan28° on both sides:          x = 8/tan28°
  4. Evaluate:                                          x = 15.0458
  5. Round:                                              x ≈ 15.0 ft
