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