Question

in the given figure ab is parallel to CD angle abe equal to 120 degree angle ecd is equal 100 degree and angle BeC is equal to X please find the value of x

Answer 1

Here is que's answer dear.

Answer 2

Answer:

Step-by-step explanation:

Let AB is parallel to FG, then ∠ABE=∠BEG=120°(Alternate angles)

Also, it is given that CD is parallel to AB and we have assumed that AB is parallel to FG, then CD is parallel to FG

Therefore, considering CD║FG and CE is the transversal, then

∠DCE+∠CEG=180°(Co-interior angles)

100°+∠CEG=180°

∠CEG=80°

Now, ∠BEG=∠BEC+∠CEG

120°=x+80°

x=40°

Thus, the value of the ∠BEC=x=40°
