Question

Find the value of x' in the given figure ABCD. pls tell me..????​

Answer 1

Answer:

it's answer should be 140°

Step-by-step explanation:

angle DCB = 180 °- 70° = 110°

angle CBA = 180° - 80° = 100°

angle BAD = 180°- 70° = 110°

sum of all angles = 360°

and, sum of angle DCB + angle CBA + angle BAD + x° = 360°

now, angle CDA = 360°- 320° = 40°

so, angle CDA + x = 180°

40°+x =180°

x = 180°- 40°

x = 140°

Answer 2

Step-by-step explanation:

80 + 80 + 70 +x = 360

232 + x = 360

x = 360 - 232

x = 128 is the ans.

hope this ans. will help you dear...
