  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

Step 1: Identify

Angle θ = y

Opposite Leg = 8

Adjacent Leg = 10

Step 2: Solve for y

  1. Substitute [Tangent]:                    tan(y) = 8/10
  2. Simplify:                                         tan(y) = 4/5
  3. Inverse Trig:                                  y = tan⁻¹(4/5)
  4. Evaluate:                                        y = 38.6598
  5. Round:                                           y ≈ 39°
