140, 40, 20, 160

270, 150, 30, 20

40, 70, 90, 60

110, 40, 30, 80​

Answer 1

Answer:

(a) We know that, the sum of interior angles of a quadrilateral is 360°. Thus, the angles in option (a) can be four interior angles of a quadrilateral as their sum is 360°.

Answer 2

(a)

Step-by-step explanation:

Sum of interior angle of all polygons is 360°

Only in option (a) sum of all angles is 360°

Hence answer is (a)
