Question

please give correct answer ​

Answer 1

Answer:

140°

Step-by-step explanation:

1) regular polygon is one in which all angles are equal i.e equiangular and all sides are equal i.e equilateral

2) here x =

according to linear pair the angle adjacent to 90° = 180-90 = 90°

we know that in any quadrilateral sum of interior angles is always 360°

so, x+90+60+70 = 360

= x+220 = 360

= x= 360-220 = 140°

therefore x = 140°
