Answer: The angle of depression is 51.34°.


Explanation:

1. You can make the diagram shown in the figure attached. Where
A is the point where the clue is and
B is the point where Tyler is.

2. To calculate the angle of depression, which is identified in the diagram as
\alpha, you can use
tan^(-1), as following:


tan^(-1)(\alpha)=(3.5)/(2.8)

3. Then, you obtain the following angle of depression from the clue to the point where Tyler is:


\alpha=51.34°
