Question

Here AB|| CD . Find x​

Answer 1

Answer:

108

Step-by-step explanation:

since this forms a triangle

Answer 2

Draw a line parallel to AB and CD named RO

If, AB || CD then, AB || RO || CD

Now, ∠B + ∠BOR = 180

= 130 + ∠BOR = 180

= ∠BOR = 180 - 130

= ∠BOR = 50

Now, ∠D + ∠DOR = 180°

= 122 + ∠DOR = 180

= ∠DOR = 180 - 122

= ∠DOR = 158

At last, ∠DOR + ∠BOR = ∠O

= 158 + 50 = ∠O

= 208 = ∠O

And finally we have got our answer. :P
