- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Explanation:
Step 1: Identify Variables
Angle = 8°
Adjacent = 12
Hypotenuse = x
Step 2: Solve for x
- Substitute [cosine]: cos8° = 12/x
- Multiply x on both sides: xcos8° = 12
- Isolate x: x = 12/cos8°
- Evaluate: x = 12.1179
- Round: x ≈ 12.12
