dmitriy555 [2]

Answer:

  11.06°

Step-by-step explanation:

The law of cosines can be used to find the angle. The sides adjacent to that angle are a=34, b=38, and the side opposite is c=8. Then the angle is found from ...

  c² = a² +b² -2ab·cos(C)

  cos(C) = (a² +b² -c²)/(2ab)

  C = arccos((a² +b² -c²)/(2ab))

  C = arccos((34² +38² -8²)/(2·34·38)) = arccos(317/323)

  C ≈ 11.06°

From the footballer's viewpoint, the goal posts are 11.06° apart.
