### Circle and Angle Problem

In the given diagram, we have a circle with points R, S, and T on its circumference. A line "m" extends from point R. There is an inscribed angle ∠TRS formed by line segments RT and RS which is measured to be 102 degrees.

#### Task

**Question:**
What is the measure of arc RST?

**Options:**
- A) 51 degrees
- B) 204 degrees
- C) 180 degrees
- D) 102 degrees

**Diagram Explanation:**
- The circle is split into an arc RST, and we need to find its measure.
- The inscribed angle TRS, which intercepts arc RST, is 102 degrees. 

**Hints for Solution:**
- Recall that the measure of an arc intercepted by an angle in a circle is twice the measure of the inscribed angle that intercepts it. Hence, if the inscribed angle is 102 degrees, the measure of arc RST would be 2 * 102 degrees.

**Calculation:**
Arc RST = 2 * ∠TRS
         = 2 * 102 degrees
         = 204 degrees

**Correct Answer:**
- B) 204 degrees
