Answer:

∠A = 25°

∠B = 73°

∠C = 82°

Step-by-step explanation:

∠C = ∠B + 9°

∠B = 3x - 2°

∠A = x°

∠A + ∠B + ∠C = 180° (Angle Sum property of Triangle)

Putting values

x + 3x - 2° +3x - 2° + 9° = 180°

7x + 5° = 180°

7x = 175°

x = 175°/7

x = 25°

SO , ∠A = 25°

∠B = 3x - 2° =3(25)° - 2° = 75 -2 = 73°

∠C= B + 9° = 73° + 9° = 82°
