Question

In the above glven fig. AB ICD and BC IDE, The value of x is
a. 40°b. 140° C. 180° d. 90°​

Answer 1

Answer:

140 degree

Step-by-step explanation:

Because x is equal to angle ABC so

40 + x=180

X=180-40

That is 140

Answer 2

AB||CD (Given)

BC||DE (Given)

X = ?

<D = <B (Alternate Interior Angles)

<D = 40°...(i)

X + <D = 180° (Linear Pair)

X + 40° = 180° (From Equation.. (i) )

X = 180° - 40°

X = 140° Answer....
