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

Step-by-step explanation:

Step 1: Define

Angle = 37°

Adjacent Leg = x

Hypotenuse = 10

Step 2: Solve for x

  1. Substitute [Cosine]:                    cos37° = x/10
  2. Isolate x:                                      10cos37° = x
  3. Rewrite:                                       x = 10cos37°
  4. Evaluate:                                     x = 7.98636
  5. Round:                                         x ≈ 8
