First let's start by drawing the described problem so we can better understand the procedure to follow:

In the above representation, we can see that the height of the given triangle can be determined by subtracting the height of the table from Michael's height, like this:

h = 5.6 - 2 = 3.6

Then, the triangle has the following dimensions:

As you can see, we have a right triangle, by taking the tangent of the angle θ, we get the following expression:


tan(θ)=(ol)/(al)

Where ol is the opposite leg to the angle θ and al is the adjacent leg to this angle, in this case, ol is 11 and al is 3.6, then we get:


tan(θ)=(11)/(3.6)

By taking the inverse tangent function, we get:


\begin{gathered} tan^(-1)(tan(θ))=tan^(-1)((11)/(3.6)) \\ θ=72 \end{gathered}

Then, the angle of depression is 72 degrees
