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

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use trig to find the missing side length.

Step 2: Identify Variables

POV from angle measure

Angle = 30°

Adjacent Leg = m

Hypotenuse = 12

Step 3: Solve for m

  1. Substitute [cosine]:                    cos30° = m/12
  2. Isolate m:                                    12cos30° = m
  3. Evaluate:                                     10.3923 = m
  4. Rewrite:                                       m = 6√3
