Question

The answer shuld be 80 degree but show the process​

Answer 1

Answer:

Given=AB//ED

angle ABD=30degree

angle CED=70degree

x=?

angle ABC = angle CDE by alternate interior angle because AB//ED

so, angle CDE = 30degree

In traingle CED by angle sum property

[A+B+C=180°]

70°+30°+x=180°

100°+x=180°

x=180°-100°

x=80°

angle DCE=80°
