Trigonometry

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

Step-by-step explanation:

Step 1: Define

Angle θ = 70°

Opposite Leg = x

Adjacent Leg = 6

Step 2: Solve for x

  1. Substitute in variables [tangent]:                                                                     [tex]\displaystyle tan70^\circ = \frac{x}{6}[/tex]
  2. [Multiplication Property of Equality] Isolate x:                                                [tex]\displaystyle 6tan70^\circ = x[/tex]
  3. Rewrite:                                                                                                             [tex]\displaystyle x = 6tan70^\circ[/tex]
  4. Evaluate:                                                                                                           [tex]\displaystyle x = 16.4849[/tex]
  5. Round:                                                                                                               [tex]\displaystyle x \approx 16.5[/tex]
