Question

from fig. Find ,
ip line ill line m​

Answer 1

Answer:

n = 30°

Step-by-step explanation:

Let's consider the interesting angle as ' O '

As line l is parallel to line m

angle 60° = Angle O

=> intersecting angle = 60°

2 angles formed on line ' m ' = 180°

=> angle O + other angle( inside triangle) = 180°

=> 60° + Other angle = 180°

=> Other angle = 180 - 60

=> Other angle ( inside triangle )= 120°

Sum of angles of triangle = 180°

=> 30 + 120 + n = 180

=> 150 + n = 180

=> n = 180 - 150

=> n = 30°
