1. **State the problem:** We have a quadrilateral NOPQ inscribed in circle R with angles at N, O, P, and Q given as 52°, 74°, (x-89)°, and (2y-38)° respectively. We need to find the values of $x$ and $y$.
2. **Key property:** Opposite angles of a cyclic quadrilateral sum to 180°.
3. **Set up equations:**
- Angles at N and P are opposite, so:
$$52 + (2y - 38) = 180$$
- Angles at O and Q are opposite, so:
$$74 + (x - 89) = 180$$
4. **Solve first equation:**
$$52 + 2y - 38 = 180$$
$$\cancel{52} + 2y - \cancel{38} = 180$$
$$14 + 2y = 180$$
$$2y = 180 - 14$$
$$2y = 166$$
$$y = \frac{166}{2} = 83$$
5. **Solve second equation:**
$$74 + x - 89 = 180$$
$$\cancel{74} + x - \cancel{89} = 180$$
$$x - 15 = 180$$
$$x = 180 + 15 = 195$$
6. **Final answers:**
$$x = 195$$
$$y = 83$$
