Trigonometry

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

Angle θ = 34°

Adjacent Leg = x

Hypotenuse = 4.8

Step 2: Solve for x

  1. Substitute [Cosine]:                    cos34° = x/4.8
  2. Isolate x:                                      4.8cos34° = x
  3. Rewrite:                                       x = 4.8cos34°
  4. Evaluate:                                      x = 3.97938
  5. Round:                                         x ≈ 4
