Trigonometry

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

Step 1: Define

Angle θ = 58°

Opposite Leg = x

Adjacent Leg = 8

Step 2: Solve for x

  1. Substitute in variables [tangent]:                                                                   tan58° = x/8
  2. [Multiplication Property of Equality] Isolate x:                                              8tan58° = x
  3. Rewrite:                                                                                                             x = 8tan58°
  4. Evaluate:                                                                                                           x = 12.8027
  5. Round:                                                                                                             x ≈ 12.8
