Geometry

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

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°
