The measure of angle x is 40°.

Step-by-step explanation:

  • To solve the given question, construction is required.
  • The line BA should be extended to G to cut line CE at F. (see attached figure)

  • Now, Since, AB is parallel to CD, AF should also be parallel to CD.

Hence,

∠DCF + ∠CFG = 180° ( angles on same side of transversal)

100° + ∠CFG = 180°

∠CFG = 180° -  100° = 80°

  • So, ∠EFB = ∠CFG = 80° ( vertically opposite angles)

  • Also, ∠ABE + ∠EBF = 180° (linear pair)

120° + ∠EBF = 180°

∠EBF = 180° -  120° = 60°

  • Now, In triangle BEF,

∠BEF + ∠EBF + ∠EFB = 180° (angle sum property of a triangle)

x + 60° + 80° = 180°

x = 180° -  140° = 40°

Hence, the measure of x is 40°.
