Question

in the figure AB parallel CD find the value of x with proper solved

Answer 1

draw a line parallel to both ab and CD .....
angle EAB and angle AE ext are alternate angles similarly ECD and CEext ...then make the equation and find x

Answer 2

Answer:

140°

Step-by-step explanation:

Refer the attached figure

AB  || HI || CD

Now Since AB  || HI

So, ∠BAE =∠AEH (Alternate interior angles)

∠BAE =∠AEH = 108°

Now Since HI || CD

So, ∠ECD =∠HEC (Alternate interior angles)

 ∠ECD =∠HEC= 112°

Since we know that

∠AEH+∠HEC+∠AEC=360°

108°+112°+x=360°

220°+x=360°

x=360°-220°

x=140°

Hence the value of x is 140°
