Question

find the value of x if line l is parallel to line m
want step by step answer
and i will mark you as brain list ​

Answer 1

Answer:

x = 120°

Step-by-step explanation:

x + 60 = 180  (co-interior angles)

x = 180 - 60

  = 120°

Answer 2

Step-by-step explanation:

From the figure

x+60°=180°

since the interior angles on the same side to the transversal

=>x=180°-60°

=>x=120°

The value of x=120°

Used concept:-

if two parallel lines intersected by a transversal then interior angles on the same side to the transversal are supplementary.
