In ΔPQR, ∠P = 2*∠Q and, 2*∠R = 3*∠Q
We know that sum of three angle 180 degree. i.e ∠P + ∠Q + ∠R = 180
∠Q = ∠P/2...(1)
And, ∠R = 3*∠Q /2
or, ∠R = 3*∠P/4...(2)
Then, from the values of (1) and (2), ∠P + ∠P/2 + 3*∠P/4 = 180
Or, ∠P* (1 + 1/2 + 3/4) = 180
Or, ∠P = 80
From (1), ∠Q = 40 and from (2) ∠R = 60.
Answer: ∠P = 80, ∠Q = 40, ∠R = 60.
