Question

ab//cd and bc//de find x​

Answer 1

Answer:

140

Step-by-step explanation:

angle BCD= 40  (alternate interior angle) BC II DE

angle ABC =x =180-40=140 (consecutive interior angles) AB II CD

Answer 2

angle D = angle C ( because they are alternate angles)

then,angle c=40 degree

as we know in an angle the angles which are on same line their sum is 80 degree

so,

angle C + angle B= 180 degree ,

now put value of angle C

40+ angle B=180

angle b whose value is given x,then

x=180-40

x=140 degree
