• [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 angle.

Step 2: Identify Variables

POV from angle x

Angle = x

Adjacent = 16

Hypotenuse = 27

Step 3: Solve for x

1. Substitute:                    cosx° = 16/27
2. Inverse:                         x° = cos⁻¹(16/27)
3. Evaluate:                       x = 53.6588°
