There are two lines, AB and CD, which are parallel to each other. ∠AMN= 20∘. Find the value of x .
90
∠AMN = 20∘
Also, AB || CD (given) So, ∠AMN = ∠MND (alternate interior angles).
So, ∠MND = 20∘
Find the value of x, if it is given that lines AB and CD are parallel to each other.
(a) In the given figure, prove that lines lm & nq are parallel to each other.
(b) Find the value of "x” if AB is parallel to CD.
