Answer 2

Answer:

∠a= 20° ∠b= 130° ∠c = 50°

Step-by-step explanation:

In ∆ADC,

∠A + ∠D + ∠C = 180°( Angle Sum property)

=> ∠D = 180° - ∠A - ∠C

=> c = 180° - 60°- 70°

=> c = 180° - 130°

=> c = 50°

Now,

From ∆ABD,

∠B +∠A =∠ADC ( Exterior Angele Property)

∠B = ∠D - ∠A

a = 50° - 30 °

a = 20°

Again,

From ∆ ABD,

∠A + ∠B + ∠ADB = 180° ( Angle Sum Property)

30° + a + b = 180°

30° + 20° + b = 180° ( since, a = 20°)

b = 180° - 30° - 20°

b = 180° - 50°

b = 130°

Therefore, ∠ = 20°, ∠b = 130° and ∠c = 50°
