Question
Find each angle and arc measure.
**Problem 4:**

**Description:**

The image depicts a circle with points A, B, C, and D on its circumference, with point D being the center of the circle. Segment AD is a chord, and line segment BC is a tangent to the circle at point B. The measure of angle ∠ADB is 47 degrees.

**Diagram Explanation:**

- The circle has a chord AC and a tangent BC.
- The center of the circle is marked as point D.
- ∠ADB, formed by the chord AD and chord DB, is given as 47 degrees.

**Question:**

Find the measure of the angle BC (notated as \( \angle BC \)).

**Mathematical Representation:**

\( \text{m} \angle BC = \_\_\_\_\_\_
