Answer:

tanZ° = 3/4

General Formulas and Concepts:

Trigonometry

  • [Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

Step 1: Identify Variables

Angle θ = Z

Opposite Leg XY = 21

Adjacent Leg YZ = 28

Step 2: Find Trig Ratio

  1. Substitute [tangent]:                    tanZ° = 21/28
  2. Simplify:                                        tanZ° = 3/4
