What is the angle of depression of D from B, as indicated in the diagram?

Question

ScanSolve AI Tutor · Accepted Answer

To find the angle of depression of D from B, we need to consider the observer at point B looking down at point D.

Identify the observer and the object.
The observer is at point B, and the object being observed is at point D.
Draw a horizontal line from the observer.
From point B, the horizontal line is the side AB of the rectangle.
Draw the line of sight from the observer to the object.
The line of sight is the diagonal BD.
Determine the angle of depression.
The angle of depression is the angle between the horizontal line (AB) and the line of sight (BD). This angle is $\angle ABD$ .
Match the angle with the labels in the diagram.
In the given diagram, $\angle ABD$ is labeled as B2.

Therefore, the angle of depression of D from B is B2.

The correct option is B.
$\boxed{\text{B. B2}}$
