**Circle and Tangent Line Geometry Problem**

---

**Question:**

Given a circle Q with a tangent line l at point P, what is the measure of the angle formed at the point of tangency?

**Options:**
- A) 180 degrees
- B) 90 degrees
- C) 45 degrees
- D) 100 degrees
  
---

**Explanation of Diagram:**

The diagram illustrates a circle labeled Q with a tangent line (l) touching the circle at point P. The radius of the circle from its center to point P is drawn, forming a right angle with the tangent line at point P.

--- 

**Answer:**

The correct answer is B) 90 degrees.

When a line is tangent to a circle, it forms a right angle (90 degrees) with the radius at the point of tangency.
