Trigonometry

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

Explanation:

Step 1: Identify

Angle θ = 35°

Opposite Leg BC = x

Adjacent Leg AC = 2

Step 2: Solve for x

  1. Substitute [Tangent]: tan35° = x/2
  2. Isolate x: 2tan35° = x
  3. Rewrite: x = 2tan35°
  4. Evaluate: x = 1.40042
  5. Round: x ≈ 1.40

Tangent (Angle) = Opposite side / adjacent side

Tangent(35) = BC/2

Multiply both sides by 2:

BC = 2 x Tangent(35)

BC = 1.40042

Rounded to nearest hundredth: BC = 1.40
