1 point

210 degree

70 degree

80 degree

90 degree

​

Answer 1

Answer:

$\huge\rm\red{Answer}$

Let the three angles be x , x , x

Sum of all angles of a quadrilateral = 360°

Therefore ,

x + x + x + 150 = 360

3x = 360-150

3x = 210

x = 210/3

x = 70

Hope it helps you

Answer 2

Step-by-step explanation:

Answer

Let the three angles be x , x , x

Sum of all angles of a quadrilateral = 360°

Therefore ,

x + x + x + 150 = 360

3x = 360-150

3x = 210

x = 210/3

x = 70
