Question

In figure, if lines l and m are parallel , then the value of x is​

Answer 1

Answer:

the value of the x is 40 degree

Answer 2

Step-by-step explanation:

since the line intersecting the parallel lines makes an angle of 90 degree therefore x+ (the angle with the base on line L) = 90 degree

similarly on line M , 125+ (the other angle on the line)= 180

or, the other angle on line m = 180-125= 55 degree

now, the other angle on line m = the other angle on line L = 55 degree (alternate angles)

therefore, x+ 55 = 90

or, x= 90-55= 35 degree... (ans)
