Answer:

24°

Explanation:

The angle between the vertical line AB and the horizontal dashed line at A is 90°. That is, ...

66° + ? = 90°

? = 90° -66° = 24°

The angle of depression is 24°.

_____

Additional comment

The sum of angles in the triangle is 180°, so the angle at C (the angle of elevation) is the same as the angle we just figured:

∠C + 90° +66° = 180°

∠C +66° = 90° . . . . . . . subtracting 90°; shows C is complementary to 66°

∠C = 90° -66° = 24°

As a rule, the angle of elevation and the angle of depression are the same.
