Question

Please tell me the step by step explanation of this ​

Answer 1

Answer:

if AB parallel CE

angle x = angle 100(corresponding angle)

angle x = 100

now in triangle ABC

100+30+Y= 180

Y =180-130

=50

angle Y =angle Z (corresponding angle)

since Option C is wrong

in option A, X=Y+Z

X=50+50

100=100

in option B, X/2 =y=z

100/2=50=50

50=50=50

in option C, 2X+Y=150

2*100+50=150

250 is not equal to 150

hence option C is incorrect
