Answer:
angle P = 80 , angle Q = 40 and angle R = 60
Step-by-step explanation:
P = 2 angle Q
2 = angle R = 3 angle Q
angle R = 3/2 angle Q
angle P + angle Q + angle R = 180
2 angle Q + angle Q + 3/2 angle Q = 180
4 angle Q + 2 angle Q + 3 angle Q by 2 = 180
9 angle Q = 360
angle Q = 360/9 = 40
angle P = 2 × 40 = 80
angle R = 3/2 × 40/20 = 60
