To solve the problem, we first need to analyze the triangle \( \Delta PQR \) with the given angles \( Q = 25^\circ \) and \( R = 65^\circ \). ### Step-by-Step Solution: 1. **Find Angle P:** We know that the sum of the angles in a triangle is \( 180^\circ \). Therefore, we can find angle \( P \) using the formula: \[ \text{Angle P} = 180^\circ - \text{Angle Q} - \text{Angle R} ...
