Using the rule of angles in parallel lines, ∠Q and ∠R are supplementary to each other
∠Q+∠R = 180°
Size of ∠Q = 25+15 = 40°
Size of ∠R = 6(25) - 10 = 140°
∠Q also supplementary with ∠P, hence ∠P = 140°
∠P supplementary with ∠S, hence ∠S = 40°
∠Q+∠R = 180°
Size of ∠Q = 25+15 = 40°
Size of ∠R = 6(25) - 10 = 140°
∠Q also supplementary with ∠P, hence ∠P = 140°
∠P supplementary with ∠S, hence ∠S = 40°
