Expert Answer:

### 2.
In triangle PQR,
angle P - angle Q = 45° and angle Q - angle R = 30°
angle P = angle Q + 45° and angle R = angle Q - 30°
angle P + angle Q + angle R = 180°
angle Q + 45° + angle Q + angle Q - 30° = 180°
3angle Q = 165°
angle Q = 55°
angle P = angle Q + 45° and angle R = angle Q - 30°
angle P = 55° + 45° and angle R = 55° - 30°
angle P = 100° and angle R = 25°

angle P = 100° and angle R = 25°
