I need to know whether the 39 m is the side adjacent to angle A or the side opposite A. Two possibilities:
- If 39 m is adjacent and 50 m is the hypotenuse:
cos A = 39/50 = 0.78 → A = arccos(0.78) ≈ 38.66° (≈ 38.7°).
- If 39 m is opposite and 50 m is the hypotenuse:
sin A = 39/50 = 0.78 → A = arcsin(0.78) ≈ 51.34° (≈ 51.3°).
Tell me which side 39 m is relative to angle A and I’ll give the final answer.
