  • [Right Triangle Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use Trig Rations to solve for the missing side

Step 2: Identify Variables

Adjacent leg = x

Hypotenuse = 16

Angle ∅ = 50°

Step 3: Solve for x

  1. Set up equation:                    cos50° = x/16
  2. Isolate x:                                 16cos50° = x
  3. Evaluate:                                 10.2846 = x
  4. Rewrite:                                   x = 10.2846
