45.6 degrees
Explanation



First of all this needs to be recognized as a right triangle problem. The angle of depression is the angle outside the triangle that is complementary to the vertex angle (the angle at the top). Geometrically, this angle is congruent to the base angle inside the triangle (NOT the right angle).
