The angle measure, or angle of depression, between the first bird and the birdwatcher, is (C) 40.8°.

<h3>What is the angle of depression?</h3>
  • The angle of depression is the angle formed by the horizontal line and the item as seen from the horizontal line.
  • It is mostly used to calculate the distance between two objects where the angles and distance from the ground are known.
  • For example, if you're standing on the ground and looking up at the peak of a mountain, you may calculate the angle of elevation.
  • The angle of depression is defined as the angle formed by the horizontal line of sight and the downward line of sight to an object.

To find the angle of depression in the given situation:

  • First, we must sketch the problem. The graphic linked depicts the right triangle generated by these three birds using each supplied value.
  • It is critical to understand that the angle of depression is the angle formed by the horizontal and diagonal at the top, as shown in the image.

We now employ trigonometric reasoning, notably the tangent function, which connects both legs.

  • tan(x)=\frac{49.6}{57.4} ≈ 0.86
  • x ≈ tan^{-1} (0.86)
  • x ≈ 40.8^{o}

Therefore, the angle measure, or angle of depression, between the first bird and the birdwatcher, is (C) 40.8°.
