find the angle of depression from point a to point c. angle of depression = ?°

Explanation:

Step1: Recall angle - depression property

The angle of depression from point A to point C is equal to the angle of elevation from point C to point A. In right - triangle ABC, the angle of elevation from C to A is complementary to the given non - right angle in the triangle.

Step2: Calculate the angle

Since the non - right angle in right - triangle ABC is 55°, and the angle of depression (let's call it $\theta$) is related to this angle. The angle of depression $\theta = 55^{\circ}$ because the angle of depression from a horizontal line at point A to point C is equal to the angle of elevation from point C to point A, and in the right - triangle formed, the angle of elevation from C to A is 55°.

Answer:

55
