SUMMARY
The speed of the bird flying at a 60-degree angle is calculated to be 240 meters per hour. This conclusion is derived from the relationship between the man's speed of 120 meters per hour and the angle of elevation using trigonometric principles. By applying the tangent function and the Pythagorean theorem, the solution confirms that the bird's speed can be determined through vector analysis and triangle properties, specifically leveraging the characteristics of 30-60-90 triangles.
