Trigonometry

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

Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = 37°

Opposite Leg = x

Hypotenuse = 25

Step 2: Solve for x

  1. Substitute in variables [sine]:                                                                           sin37° = x/25
  2. [Multiplication Property of Equality] Multiply 25 on both sides:                    25sin37° = x
  3. Evaluate:                                                                                                           15.0454 = x
  4. Rewrite:                                                                                                             x = 15.0454
  5. Round:                                                                                                               x ≈ 15
