Trigonometry

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

Angle θ = 35°

Opposite leg = x

Hypotenuse = 16

Step 2: Solve for x

  1. Substitute in variables [Sine]:
    \displaystyle sin35^\circ = (x)/(16)
  2. [Multiplication Property of Equality] Isolate x:
    \displaystyle 16sin35^\circ = x
  3. Rewrite:
    \displaystyle x = 16sin35^\circ
  4. Evaluate trig:
    \displaystyle x = 16(0.573576)
  5. Multiply:
    \displaystyle x = 9.17722
  6. Round:
    \displaystyle x \approx 9.2
