- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle Measure = 60°
Adjacent Leg = 9
Opposite Leg = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [tangent]: tan60° = x/9
- Isolate <em>x</em>: 9tan60° = x
- Rewrite: x = 9tan60°
- Evaluate: x = 15.5885
- Round: x ≈ 15.6
