Question

please tell the c part fast​

Answer 1

Answer:

70°

Step-by-step explanation:

since A=B=C

A+A+A+150°=360°

3A=360-150

3A=210

A=210/3

A=70°

Answer 2

Answer:

70°

Step-by-step explanation:

Since A = B = C

A = B = C  = x

x + x + x + 150° = 360°(Interior angles of a quadrilateral sum upto 360°)

3x + 150° = 360°

3x = 360° - 150°

3x = 210

x = 210/3

x = 70°

Therefore, A, B, C measure 180°
