Answer 2

Answer:

Let us suppose the angles P, Q, R of a ΔPQR be x°, (x - 20)°, (x - 40)° respectively.

P + Q + R = 180∘ (Angle sum property)

⇒ x∘ + (x - 20)° + (x - 40)° = 180∘

⇒ 3x - 60° = 180°

⇒ 3x = 240°

⇒ x = 80°

Therefore,

P = 80∘

R = (80 - 20)° = 60∘

Q = (80 - 40)° = 40∘

Hence, the measure of each angle is 80∘, 60∘ and 40∘ respectively.
