Question

m
In the figure, if line l || mand
with the given information
the value of y is ... .
30°
70°
Ало
(B) 30°​

Answer 1

Since l || m , x = 70° ( Corresponding angles)

Let angle ABC be z

z + x = 180° ( Linear angle)

or z = 180° - 70°

or z = 110°

In triangle ABC, By Angle Sum property,

30° + y + 110° = 180°

y= 40°
