please tell the answer​

Answer 1

Answer:

Dude Mark me as a Brainlist plz.

x°=70°

Step-by-step explanation:

bcoz sum of all the exterior angles of any polygon is 360°

here

90°+90°+110°+x° =360°

290° +x° = 360°

x° = 360°-290°

x° = 70°

Answer 2

Answer:

x= 70°

Step-by-step explanation:

Sum of all angles in a quadrilateral = 360°

∠A = 180 - 90 = 90

∠B = 180 - 90 = 90

∠C = 180 - x

∠D = 180 - 110 = 70 ....(∵ sum of angles in a staright line is 180°)

∴ => ∠A + ∠B + ∠C + ∠D = 360

=> 90 + 90 + (180 - x) + 70 = 360

=> 180 + 180 - x + 70 = 360

=> 360 - 360 + 70 = x

=> 70 = x

∴ => x= 70° (Ans
