Final answer:
The measure of angle L is approximately -2.12°.
Step-by-step explanation:
The measure of angle L can be found by subtracting the given angles.
- Angle 0₁ = 20₁ = 2(14.5°) = 29°
- Angle 0₂ - 0₁ = 30.05° - 14.5° = 15.56°
- Angle L = 29° - (2 × 15.56°) = 29° - 31.12° ≈ -2.12°
Therefore, the measure of angle L is approximately -2.12°.
