Is the answer please give rating

Answer 2

Answer:

a = 20°

b = 130°

c =50°

Step-by-step explanation:

NOTE :

• Sum of all the angles of triangle = 180°
• sum of angles on the straight line = 180°
• In the given question there arethree triangles.
• ADC, ABD and ABC

In triangle ADC

Angle DAC + angle ACD + angle ADC = 180

=> 60 + 70 + c = 180

=> 130 + c = 180

=> c = 180 - 130 = 50°

Line BDC

Angle BDA + angle ADC = 180

=> b + 50 = 180

=> b = 180 - 50 = 130°

In triangle ABD

Angle ABD + angle BAD + angle ADB = 180

=> a + 30 + b = 180

=> a + 30 + 130 = 180

=> a + 160 = 180

=> a = 180 - 160 = 20°
