Trigonometry

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

Angle = 8°

Adjacent = 12

Hypotenuse = x

Step 2: Solve for x

  1. Substitute [cosine]:                     cos8° = 12/x
  2. Multiply x on both sides:            xcos8° = 12
  3. Isolate x:                                      x = 12/cos8°
  4. Evaluate:                                      x = 12.1179
  5. Round:                                         x ≈ 12.12

Answer:

X= 12.12

Step-by-step explanation:

The answer is 12.12 for x
