Question

k) In the adjoining figure find the value of a, ​

Answer 1

Answer:

5a+a = 180 ( co-interior angles)

6a=180

a=30°

Answer 2

we know that, when a parallel line is cut by an other line, the interior angles of the same side together form 180°..

so,

5a+a=180

=>6a=180

=>a=180/6

=>a=30

so, the value of a is 30°
