Question

24) In figure, AB || CD, the value of x is:
(a) 35°
(b) 40°
(c) 60°
(d) 750
​

Answer 1

In the given figure 'O' is the common vertex and OB is the common arm. Hence, ∠a and ∠b are called the adjacent angles. Linear Pair: A pair of adjacent angles is called linear pair, if their two non-common arms are opposite rays. Here adjacent ∠A and ∠B are linear pair The angle sum of a linear pair is equal to 180o.
