In figure, if 1 ll m, then x=​

B

y = 55 => x = 180-55=125

x=125

Step-by-step explanation:

55 and y are corresponding angles and when the lines are parallel corresponding angles are equal

y = 55

x and y are supplementary angles which means they add to 180

x+y = 180

x+55 =180

x = 180-55

x =125
